Roll up tonneau cover for GMC 2500HD Short Bed

Hi Everyone!

I used to have a '08 GMC 2500HD short bed with an Extang RT low profile tonneau cover on it. We towed a 30ft Weekend Warrior 5th wheel with it. Worked fine, until I impacted the rails of the cover with the hitch pin on a couple tight turns. One time, just left a dent in the rail, 2nd time, ripped it off completely.

Currently have a '13 GMC 2500HD (same body style) and tow a 30 ft Cougar with it, and currently searching for a roll up tonneau cover for it.

I really like the Truxedo Lo Pro, and X15 series (have an X15 series on my Colorado), but am concerned about impacting the rails for the tonneau cover, since they are low profile, they mount inside the bed.

Secondly looking at a cover that mounts on the bed rails, but I really don't like the look and don't really want to narrow the clearance between the rails and 5th wheel.

Kinda of hard to try these covers out before hand, and they are expensive to buy one that might not work.

Anyone have any experience with the Lo Pro and/or X15 on a GM 2500HD short bed towing a 5th wheel? Issues or impacts/damage the cover rails? Or any thoughts on the best option for a roll up cover?

Thanks!
  • Can’t comment on the roll-ups your interested in, but want to suggest an alternative. I’ve had a 3-fold TonnoPro on my 2013 Silverado SB for 8 years and love it. It was less expensive than most. The soft vinyl cover holds up well (3-4yrs of snow in MN winters). I flip fold it to the front when running with the 5er. It doesn’t require any additional rails or hardware that impinges on the bed opening. Give it a look.
