I can't help you with the "good and bad about the Raptor" but can welcome you to the forum. As a quick observation and without any numbers to work with, it seems that the combination of that Raptor and the Chev will put you close to the maximum tow limits of the 2500HD. Towing that beast will make your gasser thirsty!

to the forum and to toyhauling. As you've already found, that's one heavy trailer and a "tough pull" for a gas engine. One way you can improve your fuel mileage is to plan all your towing to be downhill with a tail wind <wink> but if that's a tough thing to do, maybe look at improving your rear axle ratio ??? No idea what you have currently, but would guess it's in the 3.55 to 3.73 range. Possibly changing to 4.10 to 4.55 or so gearing would improve your performance. But, doing that may cost more than trading for a better equipped truck that already is set up for your towing needs.

As a current "light duty tower" I'm out of the loop with RV's as heavy as yours, but in "days past" about the only way I'd tackle a trailer that heavy would be with a diesel.

Anyway, welcome to the forum and I'm sure other members will be offering their observations and recommendations.

My mileage goes to nearly half when I hook up my 7000 lb fifth wheel. Normally I get about 18 to 20 solo depending on how and where I drive. With the trailer attached, it's down to about 9.8-11 usually and maybe even a little less if it's a "hard pull" in hills or a headwind. I've seen a 15 MPH headwind cut mileage by 1-2 MPG but I've never seen a tailwind of the same strength improve it that much LOL

It takes a lot of work to move an RV that size down the road and work takes fuel. I don't have any other suggestions on what to do to improve your mileage. Some may suggest a chip, exhaust, intake modifications, but I'm thinking they will be of negligible help when under that kind of load.

Welcome to the group and forget about fuel mileage when RV'ing. They are mutually exclusive of one another
