LEER 100XR Review: A Great-Looking Cap, as Dry as Its Install

Buy the LEER 100XR if you want a fiberglass cap that's molded for your truck, painted to match it and built with the options you pick: sliding side windows with screens come standard, and windoors, side-access doors, keyless entry and Thule roof tracks are on the list. It's the cap we'd look at first among the paint-matched fiberglass shells. LEER builds each one to order and sells it through dealers, not Amazon, so we earn nothing when you buy one.

Go in knowing how much rides on the dealer. LEER warrants the fiberglass structure and the paint for as long as you own the cap, but only when an authorized dealer installs it on the original truck, and the locks, latches and brake light get one year. Whether your bed stays dry depends on how the cap was cut and sealed at the factory and how carefully it was set, sealed and adjusted at install. Don't confuse it with LEER's 100XQ, 100XL, 100R, 180 or 122; those are different caps.

The short version

What works:

• Fit and looks: a one-piece shell molded for one make, model and body style, with frameless compound-curved rear glass and paint matched to your truck's color.
• Ventilation: sliding side windows with screens are standard, and the windoor options open the sides for reaching into the bed.
• One handle at the back: a single flip-lock handle and rotary latches instead of a lock on each side of the door.
• Warranty on what matters most: lifetime coverage on the fiberglass structure and against abnormal paint fade or peel, for the original buyer.
• A dealer network: the dealer that sells it handles warranty claims and adjustments, and LEER has stood behind repaints, new windows and replacement shells.

What to watch:

• Leaks: most owners see at least some water, usually at the rear door and tailgate, around holes cut for hardware, or at the windows.
• Quality on delivery: scratches, a misplaced rack track or a badly cut hole are common enough that you should inspect the cap before you pay.
• Roof load: LEER publishes limits for its factory Thule racks only, and its own pages disagree; there's no published rating for the roof itself.
• Waiting: it's built to order, so plan on weeks to months.
• Hardware coverage: locks, latches, the brake light and factory accessories get one year; gas props get five.

Which trucks and beds it fits

LEER builds the 100XR to fit one truck. Its FAQ says most LEER molds fit only the make, model and style they were designed for, so a cap off another truck is a gamble. We checked LEER's fit tool year by year on October 24, 2026, and it lists the 100XR for every year below:

• F-150: 2015-2020 (Gen13) and 2021-2026, the 14th-generation F-150 (Gen14).
• Silverado 1500 and Sierra 1500 (T1XX): 2019-2026. GM also sold the old body as a 2019 and a 2022 model, and LEER's tool doesn't separate them, so tell the dealer which one you have.
• Ram 1500 (DT): 2019-2026. LEER lists the Ram 1500 Classic as a separate model.
• Tacoma: 2016-2023 (3rd gen) and 2024-2026 (4th gen).
• Tundra (3rd gen): 2022-2026.
• Ranger (6th gen): 2024-2026.
• Maverick: 2022-2026.
• Colorado and Canyon (3rd gen): 2023-2026.

The tool asks for cab and bed length, but its answer doesn't change when you change them, so treat it as a yes for the truck, not for your exact bed. The dealer confirms the cab and bed when they quote the cap, and that's also where you find out which options your truck can get. LEER says door configurations, toolbox options and features vary by model, model year and bed. Its 100XR page says nothing about RamBox or the GM MultiPro and Multi-Flex or Ram multifunction tailgates, so ask before you order if you have one. One F-150 owner's first installer cut the bedliner to make the cap fit, so if you run a drop-in liner, ask how the dealer will handle it before the cap goes on.

The specs that matter

LEER publishes the features but not the numbers most buyers ask for: no weight, no install time and no load rating for the roof itself. Here's the 100XR against the caps it gets shopped against, from each maker's own page:

The missing weight matters for payload. LEER doesn't print it, so get it from the dealer or a scale ticket and count it along with everything on the roof and in the bed. One 2020 Tacoma owner says the shell alone changed nothing, but the rear sagged once other people's gear and passengers went in too.

Roof racks and rooftop tents

This is where we'd be most careful. LEER's FAQ says a factory-installed Thule Tracker II on a 100XR carries 165 lb at most and a Thule AeroBlade 220 lb. The safety tips on its warranty page give factory Thule racks one 165 lb limit, and the 11/24 printed warranty card says 150 lb. None of them says whether the figure is static or for driving, and the current 100XR page lists the Tracker II, WingBar and ProBar but not the AeroBlade. Plan on 150 lb, the lowest figure LEER prints, until your dealer gives you a higher one in writing for the rack on your cap.

LEER publishes no separate rating for the cap roof while you're parked, so there's no LEER number for a rooftop tent with people in it. Owners quote figures from 150 lb to several hundred, and some have run tents up there for a year or more, but none of those numbers is LEER's, and a parked rating is not a driving rating. LEER also says aftermarket racks may need bolt plate reinforcements it sells, and Thule wants front and rear tie-downs on long loads like a kayak or canoe. If a tent is the plan, we'd put it on a bed rack that bolts to the truck, not on the cap, or look at a cap whose maker publishes a parked load. SmartCap rates the EVO Sport at 770 lb parked and 330 lb moving and still warns that the truck's bed may be the lower limit.

If you camp under the cap, LEER's rule is short: no one rides in it while the truck is moving or the engine is running.

Weather sealing and leaks

Expect some water unless the install is very good. The fiberglass shell itself doesn't leak; the joints do. The rear door glass has to press evenly into its seal, and when a latch is off or the cap sits too far forward or back, rain runs past the bottom corners and down the tailgate. Every hole cut in the shell is another seal, and the worst leaks trace to holes: a third brake light opening cut far too big, roof hardware for rack tracks and rod holders that leaked on day one, side windows set in their frames badly enough that LEER swapped them. Then there's the bed. Tacoma beds have seams and gaps at the front corners that let water in under any cap, and some owners have found their beds out of square from the factory.

Most of these get fixed, which is the good news. Owners have had latches adjusted, windows replaced, a cap moved on the rails and whole shells replaced under warranty, and LEER agreed to replace the 3rd gen Tacoma cap that dripped like a faucet at the rear. The bad news is the time it takes and how much depends on the dealer: a 2022 F-150's headboard leak beat two dealers, and one Tundra owner's dealer said that's what caps do, though a hose test showed the rear glass wasn't touching its side seals.

Do the prep before the cap goes on and the test before you drive off. Seal the bed seams and front corners while the bed is bare, add a tailgate seal, then run a hose over the roof, windows and rear door and open it up to look for wet spots. Keep pressure washers off it: LEER doesn't warrant the windows against leaks from high-pressure car washes and asks you to skip commercial and high-pressure washes for the paint's first 90 days.

Build quality and living with it

The shell is the strong part, and the paint match is why owners choose it. LEER is upfront that nobody can guarantee an exact match to factory paint, but owners who picked the 100XR over an A.R.E. or a SmartCap usually did it for the look, and paint-match complaints are rare next to complaints about what's bolted to the shell.

• Arrival defects: scratched paint, a dented roof, rack tracks mounted on the wrong sides. Dealers have fixed these with paint correction, refunds or a new shell, but check every panel before you pay.
• Struts: the rear door and windoor gas props wear out; one owner replaced them after about eight years. LEER covers gas props for five.
• Locks and handles: the single handle is easier day to day, but keyed locks can freeze in winter, and one owner who has had both says the XR's handle wears out sooner than the plain 100's. Those parts get one year of coverage.
• Windows: sliding windows can be stiff until they're lubricated, and the windows and doors draw most of the long-term complaints.
• Paint: a 2014 cap that started bubbling around its Thule tracks and windoors went back to LEER for a full repaint under warranty years later. The powder-coated latch was not covered.

Lead times swing widely because nearly every cap is built to order, at one of three LEER plants. Owners report about five weeks from order to install at the fast end and 19 weeks at the slow end, and quotes often run short. Order early if you need it by a date.

How it compares

• Versus the LEER 100XQ: the step up in the same family. One-piece tip-out side windows, hidden rear-door hinges, and a headliner with an insulated roof as standard. LEER's page lists no windoors or sliding side windows for it, and LEER's fit tool doesn't list it for the 3rd gen Tundra. Buy the XR if you want sliding windows or windoors for ventilation and side access.
• Versus the A.R.E. CX Classic: the closest rival: paint-matched fiberglass with a lifetime body and paint warranty, an aluminum-framed rear door and framed sliding windows. A.R.E. covers the lock, keyless entry and brake light for three years to LEER's one. One Tacoma owner who ran an A.R.E. CX Evolve and then a 100XR calls them not much different: the A.R.E. leaked at the windows and was refunded, and the LEER leaked until LEER replaced every window. We'd pick on the dealer, the price on your truck and whether you want frameless rear glass.
• Versus the SmartCap EVO Sport: stainless steel with gullwing side doors and published loads of 770 lb parked and 330 lb moving, so it's the one for a rooftop tent or real roof loads. It has a 3-year warranty and costs noticeably more on the trucks owners priced.
• Versus a Softopper: our Softopper review scores that canvas topper higher, and we stand by it. Owners report water under each about as often, but the 100XR's bad leaks take a dealer or the factory to fix, and it costs far more. Buy the 100XR for locking doors, a roof rack LEER rates and a shell that looks like part of the truck, not for a guaranteed dry bed.
• Versus a tonneau cover: a cover keeps the bed low and the rear view clear; a cap gives you standing-height cargo room and windows. Our tonneau cover vs camper shell guide walks through that choice.

Installing it

Let a dealer do it. LEER says it authorizes and warrants only installs by authorized LEER dealers, and the structure and paint warranty depends on it. Find one with LEER's dealer locator. The cap clamps to the bed rails with J-bolt clamps over a bulb seal, and LEER calls its 7-way harness the recommended installation option. LEER's install instructions and your dealer govern the job, including any drilling for wiring or corner braces.

Check the work before you leave. The front of the cap should sit square to the front of the bed and the rear door should latch with even pressure all the way around; one 5 ft Tacoma cap set too far back rubbed paint off the bed wall the first day. Protect the painted bed rails where the cap sits, since LEER counts paint wear there as normal wear. Afterward, LEER asks you to check the mounting hardware monthly, lubricate windows, hinges and locks, and have the dealer check the clamps once a year.

Who should order a 100XR

Order one if you want a cap that looks like it came with the truck, you'll use the windows and side access, and you have a dealer you trust to install it and stand behind it. We'd add windoors on at least one side, a removable front window so you can clean both pieces of glass, and a tailgate seal, and we'd hold the dealer to a water test before paying the balance.

Skip it if you need to carry real weight on the roof, especially a rooftop tent, or you need a cap next month. The SmartCap carries far more on top, and an A.R.E. CX Classic is the like-for-like alternative if your A.R.E. dealer is the better shop. LEER sells the 100XR through dealers and we earn nothing on it; it's still the paint-matched fiberglass cap we'd start with.
