Anyone pull a 14k 5er with a gas engine

My fifth wheel is close to 12,000 lbs & my truck pulls it very well. Power wise another 2000 lbs wouldn't be that bad on flat roads, but the truck would be badly overloaded. A 14,000 lb fifth wheel will have about 2800 lbs on the pin, plus hitch, plus passengers, plus gas, plus other stuff. A one ton would do it.

Personally though, I'd go with the diesel.

As long as your comfortable hearing that gasser pulling really high rpm's (sometimes 4-5k) on hills, climbs, and headwinds, yup, it'll do the job. A diesel will do it with less strain on the engine, tranny, and your senses. I'd guess you get about 6-7 mpg's pulling 14.5k with a gasser.

FWIW, a Ram 3500 6.4 gasser is rated to pull 16k or so with the 4.10 rear end. Payload for a Ram 3500 SRW is at least 4,000 lbs.---considerably higher for the dually.

Absolutely, I have pulled two fivers one at 11,300 loaded and the second at 12,200 loaded with a 2500 HD GMC Big Block 496 cu.in and Allison 5 spd trans, also had air bags on the rear axle, u8sing a SuperGlyde 16K hitch... Towing mpg 8 to 10 mpg Enjoy your camping!!!!

I don't but I have pulled slightly smaller trailers with a gas engine. We upgraded to a diesel in 2004. Get the diesel you won't regret it. with a gas rig you will regret it . My guess would 6-7 mpg with gas. 9 to 11 mpg diesel.
Our Fiver weighs 13,900 loaded. I would not want to pull it with a gasser .

No, I think you are over the payload weight on the sticker on the drivers door post.
You know the one that none of us ever read but rely on the salesman's words instead.
I am not being snarky but most do it.
You will have a pin weight of about 1500 lbs plus the weight of the hitch assembly you will be about 1800 pounds payload before you put anything in the truck including people. What mods do you plan for the Tahoe?

Sure, it can be done. I used to tow trailers that weight, and more, with a 1/2 or 3/4 T truck on the farm all the time. With no brakes and on dirt roads, too. Yes, it was only a few miles and generally at no more than 30 mph. :B Will all depend on how far you're going and the terrain involved. Flat country for 100 miles? I'd do it. Here in AZ, heading to the mountains? Only if there was no other way.
