Talk to me, please. Would a 5th wheel that weighs 9,612 dry weight... with a hitch/pin weight of 1850... be too much... or towing the line... or reasonable?
RevRon, I'd guess with the specs provided you might end up being close to your truck's capacity. What we don't know is the payload and actual weight of your truck. Payload is listed on your door pillar sticker. Getting the truck weighed at a CAT scale - fully loaded up in "travel mode" with full fuel, people, stuff, etc. - will give you solid info to plan from. Payload has been well explained, and you need to consider what weight will be over your rear axle, which I assume (like my 2022) has a GAWR of 6,040 lbs.
My 5'r is 7,720 dry with a 1,750 hitch weight as built (or empty). The hitch weighs 250 lbs - autoslider for short bed. I had two CAT weighs done - without & with trailer, but in "travel mode." Without the trailer I was at 3,620 on the rear axle. With the trailer I am at 5,520. The 5,120 on front & 5,520 on rear technically put me 640 lbs over the 10,000 lbs weight rating, but the weight on the rear is 520 under the rear GAWR. Lots of discussion out there about exceeding GVWR, etc., so I'm not trying to get into that topic. I am confident and comfortable with my setup.
Don't rely on the unloaded pin weight. That will go up as you load up the 5'r. I suggest you plan on 20 percent of the gross weight of the 5'r as actual pin weight to determine if you will exceed rear GAWR - and don't forget to add in the weight of the 5th wheel hitch you will install. I recommend you get a CAT weigh of your truck done, so you will have better into to plan from. Your gasser will have more payload than does my diesel, but both will have the same 10k GVWR and rear 6,040 GAWR.
BTW - I had three bumper-pull trailers (each progressively larger) over the past 20 years. Moved up to the 2500 & a 5th wheel. Really prefer the 5'r over a bumper-pull for lots of reasons.
