Truck Bed Camper for GMC Sierra 1500

How it fits
Why a Kimbo works on a GMC Sierra 1500.
The Sierra 1500 is the GMC-badged twin of the Silverado 1500 — same frame, same suspension, same bed. For Kimbo fit purposes they're identical, but Sierra's trim ladder skews more upmarket, which matters because the most-aspired-to Sierra trim, Denali, is the one we have to flag for camper buyers.
**Denali** is gorgeous but it's the lowest-payload Sierra in the lineup. The combination of factory sunroof, 22" wheels, and the standard tow package brings curb weight up while keeping GVWR fixed — door-jamb stickers on Denali Crew Cabs typically read in the 1,500–1,600 lb range, which is the bottom edge of the Kimbo 8 install zone and uncomfortably tight for full payload usage. We don't say no to Denali installs, but we want to verify the specific truck's sticker before committing.
**SLE, SLT, AT4, and AT4X** trims are the Sierra sweet spots for Kimbo. SLT and AT4 carry meaningful payload margin (1,900–2,200 lb on most configurations) and the AT4 off-road suspension package is well-suited to camper loading. AT4X (the off-road performance trim) sits taller on Multimatic shocks and may need jack-bracket extensions, but the truck handles a Kimbo 8 well. The 6.5' Standard Bed is what we recommend on any Sierra Kimbo install — meets K8 minimum, lets K6 close the tailgate.
By generation
Year-by-year fit notes.
Truck-camper fit isn't one-size-fits-all across model years — frame, cab clearance, and suspension change between generations. Here's where each GMC Sierra 1500 sits.

The math
Your payload margin, calculated.
Real numbers for a fully-provisioned Kimbo install on a GMC Sierra 1500 at the middle of its payload range. Substitute your own door-jamb sticker for a precise calculation.
Calculating for
- GMC Sierra 1500 payload (mid-range)+ 1,990 lb
- Kimbo 6 (base)− 830 lb
- Fresh water (4 gal)− 32 lb
- Propane (20 lb tank)− 30 lb
- Gear load− 100 lb
- 1 occupant in cab (200 lb)− 200 lb
Remaining margin
+798 lb
Calculated using the midpoint of the GMC Sierra 1500's published payload range. Your specific truck's door-jamb sticker is what counts. Trim packages, options (sunroofs, larger wheels), and tow packages can swing this number by 200–500 lb in either direction.
The Kimbo team's pick
If we were buying a GMC Sierra 1500…
If we were buying a Sierra 1500 for a Kimbo, we'd get a T1 SLT or AT4 Crew Cab with the 6.5' Standard Bed and the Max Trailering Package. Skip Denali unless you've already ordered one — its luxury options work against camper margin. AT4X if you specifically want the off-road dynamics. Airbags and E-rated tires regardless of trim.
