Without having driven them all, the 6.6 is so far a prety decent truck. I would price some out in your area. I got the chevy because it was cheaper and more readily available then the gmc. My last 2 trucks were new gmcs. Just looking around, and depending on options, a lt 4x4 2500 chevy can be had for 51000 around my area. Not sure if you can talk them down now adays. Look around, price them out and sit in them. Then decide. Any would be more then adequate for your TT.

Get the 3/4 ton for much larger fuel tank. If you like the Ford better and it's cheaper, buy that 7.3L/10-speed. Overkill? No one said than when towing a TT. More power and more gears typically means lower fuel consumption and better towing experience, power when you want it.

No one mentioned rear gear ratio which is as important as torque and transmission if you are towing and don’t want to be hunting a lower gear all the time

Whatever you get, get the lowest gear available. this will allow towing in OD with the weight you are saying.

I had a Ram 2500 with the 6.4L Hemi and 4.10s that I pulled a 37 foot 5th wheel with. It would not run in 6th (same as you) unless I had a heck of a tail wind. It would run in 5th or 4th however, with a decent RPM spread between the two. The reason I am telling you this is because running in 4th (higher RPM) or 5th (lower RPM) didn't make much difference on the "instant" mpg display. So shooting for running in the highest gear is really no goal to shoot for.

Now, if the only way you can pull a load is with the engine screaming near redline constantly (not just during up grade pulls)_that's different. But I really don't think you're going to gain much making the swap you are considering. I'm no diesel fan boy, but it's simply a fact that they pull heavy loads much easier, and at lower RPM, and will get better mpg when comparing apples to apples. I lost about 20 to 25% going from the Cummins to the Hemi, but was still very satisfied.

The 2500 series truck is much better suited to towing, but you won't notice a huge difference in power, though there will be an increase.

So, my choices are:

GMC Sierra 1500 6.2L 3.73 420/460 DFM (don't want DFM) 26gal. One of the more pricier choices.

GMC Sierra 2500HD 6.6L 3.73 401/464 36 gal. Middle of the road in price.

Ram 2500HD 6.4L 3.73 410/429 31 gal. Weird thing is, the model is Big Horn, but can't seem to get Big Horn package with crew cab and 6 1/5 ft bed. So, one of the more pricey, comparable to the Sierra 1500.

Ford 2500HD 7.3L 3.55 430/475 36 gal. Cheapest (by about 4K pre-tax).

All are about the same size, within an inch or so in every dimension, and within a couple hundred pounds in payload and towing - with Ford leading the pack but not by much. The 1500 is smaller by a bit, quite far behind by at least a thousand in payload and 2500 in tow, and does not have an HD engine, of course.

Although we will be looking at getting a bigger trailer, I doubt we will get even close to 3500 territory, which is why I listed the 2500s.

Regarding mpg, while I, like everybody, would like to get super decent mileage, a decent ride and tow is priority.

Thanks to everyone, I have been learning a lot.....but still can't figure out why the smallest(L) engine has more hp/torque than the bigger HDs. Go figure.

JMHO, but any of the three 3/4 tons would do the job nicely. Pick the one you like best.

I'd skip the 1500 series just because of the chassis limitations. the GM 6.2L is a very strong engine.

The HD engines will make more hp and tq at lower RPM by design. It's not all about peak numbers. They often have been engineered with more durability, better cooling, and longevity higher up on the priority list as engineering goals as well as they are used in HD applications.
