Tonneau Cover Recommendation for 2025 GMC Sierra 3500 Short Bed with Thinner Rails

Updated 10/22/2025 | Published 04/02/2025

Question:

Didnt know which cover to ask this question but will start here. Ive got a 5th wheel and when I make a near 90 degree turn, the 5th wheel hitch comes very close to the trucks bed side rails. Which covers that you sell have the smallest side rails? Ones that protrude into the bed the least so that the 5th wheel hitch has the least likely possibility to damage the tonneau covers rails. Thanks, Brian

Hey Brian, this is a great question. Not one we very often but the Leer Quad Fold part # LE67FR has really narrow rails that attach to the inner side of your bed rails so that would give you the least amount of affected turning clearance for your 2025 GMC Sierra 3500 short bed.

Hey Brian, how did the Leer Quad Fold cover work out with your 5th wheel when making tight turns? Your results could really help others trying to avoid bed rail clearance issues with similar setups.

@JamesonC. The cover works great. I have a Gen Y gooseneck on my Brinkley 3100 with the 5” offset ball and have no problems with the cover on near 90 degree turns
