3/4 gas truck

"do not know how to figure for the weight I know the gas will not pull like a deisel truck but I just can't see going buy a brand new"

My "pointer" is the posts above seem like good advice to me.

This gives a pretty good idea. A FW will have about 20 percent pin wt. So a 10K lb loaded weight FW will have about 2K of pin wt, plus about 200 lbs for the hitch. This would be about the limit for the 6.0 with 3.73, due to having to deduct passengers, gear, firewood,etc.

It shouldn't have any issue with the payload of a 10K loaded trailer.

Open the drivers door. There should be a yellow tag on the truck door frame. It will tell you what the payload capacity is. This is where a lot of people get overloaded with a 5th wheel. Part of that payload capacity is the weight of the hitch, passengers,, and anything else in the truck. There will also be a tag showing axle capacities, never exceed those.
There should be a tag on the 5th wheel, probably drivers side, that shows Gross Vehicle Weight Rating.There may be a smaller yellow tag on the entrance door of the 5th with cargo capacity.
If you are looking at RV manufacturer webites for weights, they may be a bit misleading. If the dealer adds a bedroom A/C, extra battery, etc. that is usually not included in published weights. My Montana HC was listed as 2175# pin weight. By the time I installed the hitch in the truck and added cargo I was about 3500# pin weight on my truck. I was about 300# overweight on a F3550 SRW diesel and traded the Ford for Ram with 4100# payload.
I previously had a Cougar XLite 28SGS and pulled it with a GMC 2500 6.0 Short Bed 4x4 with a 3.73 axle. It was barely OK in flat land but after the first trip to the Tennessee hills I traded it for the F350.

I am towing a 31' 5th wheel, loaded at about 9,300 lbs. I am under weight limits per specs for both axles on truck and trailer. It is a 2500 HD Dodge Ram with 5.7 Hemi, 2013. Does fine. No issues. Gas averages out to about 10 mpg towing, uphill, downhill, headwind, tailwind. 10 mpg. This is a LB, CC.

I towed approx a 12,000 fiver with another Dodge Ram and it towed ok on flat lands, but uphill and downhill was not good. That was also a 2500, Hemi. Too much trailer, not enough truck.

By what I read, the 4.10 rear end will pull 14,000 in a fifth wheel, but the 3.73 is rated about 3000 pounds less.
