5th Wheel Hitch Recommendation for 2011 GMC 2500 HD with 6-1/2 Ft Bed
Question:
I have a 2011 GMC 2500 HD Duramax Diesel short bed 61/2 ft bed truck. I am thinking about purchasing a 14000 lb dry weight fifth wheel camper. Since the bed is short I want a slide bar configuration and at least a 20000 lb rating . What do you suggest? Since I am handy I am considering doing the installation myself. How hard are they to install?

I personally recommend going with the Curt A20 slider, part # C16541, and Custom Base Rails, # RP56001-53.
The A20 has a gross towing weight capacity of 20,000 pounds.
The Quick Install Custom Base Rails, # RP56001-53, include brackets that mount to existing holes in truck frame, minimizing drilling and measuring.
Installing the rails yourself should not be an issue, especially when using the custom mounting brackets. I have attached an installation video for these rails on a 2012 Chevrolet Silverado. The install on your truck will be pretty much the same and this should give you a good idea the level of difficulty.
