Question:

I have a 2015 gmc Denali 2500hd diesel and I am wondering what is a safe trailer length and pin weight to pull I am not a 100 on my pin weight according to u tube videos the max payload is 2500lbs and I can pull a max of 17100 lbs fifth wheel and 13,000 on the hitch I am looking at fifth wheels that are about 38 to 40 ft long and have a dry pin weight of about 2000 lbs and a GVWR of about 14,000 is that to much for me to try and pull

I looked up the towing capacity of your 2015 GMC Sierra 2500HD with a Duramax diesel and it looks to have a 13,000 lb towing capacity like you mentioned. If the trailers you are considering will weigh less than that when loaded and ready to tow you'd be fine, but you can't exceed this number safely. The length of the trailer is not quite as important as it's really the weight that's the issue.

The Reese 20k hitch part # RP30081 that you referenced would be a great choice for a hitch though. This hitch will have more than enough capacity and has a great jaw design that will provide a solid connection that will minimize noise.

You'll need a rail kit to install the hitch in the bed of your truck. For that you'll want a custom install kit like the Reese part # RP50066-58 which will minimize drilling and install time compared to a universal kit.
