WTB GFC Camper for 2011 Silverado short bed

Looking to buy a used GFC for a short bed pre- 2013 Chevy, a 2011 Silverado. I do not know if other short bed models for other brand will work or if the campers for the newer Chevy are compatible.

Hey I’ve got a camper for a 2018 5,8 bed Silverado id be willing to sell if you’d be interested. Would need to check with GFC if the fit will work.

Sorry its for a 2019-2023 5,8 bed.
