I understand you need more info. It's a 04 GMC Denali. Yes, it's a half ton but, the 1991 Forest River Salem he is looking at has no slides and doesn't seem to weigh much more then my TT. Plus, since it's a 5th wheel with the pin in the bed of the truck which is better then on the bumper like my TT has I believe he can tow it on the local flat ground we have around here.

I found a listing for similar 5th wheels (1991 and 25') to what you posted and they are like 4,000# units so 20% is 800#. Even if he loaded it to 5,000 which I suspect is near its gross, its a 1,000# pin. Depending upon his truck this is very doable. I'd figure around $1000 for the hitch installed. I'd just have him weight his truck 1st. Open the drivers door and look for the GVWR sticker probably GVWR (6,100#) - truck actual weight (with people, camping stuff and fuel) = remaining cargo capacity for 5th wheel. Saw a generic curd weight of 4,100# in one listing so if he verifies his numbers he should be good to go. That year truck was rated for about a 10,000# trailer.
When looking at 5er's most trucks run out of cargo capacity to carry the pin weight (avg 20%) before they run out of towing capacity.
Good luck and be safe.
