Best towing vehicles for best MPGs

I actually tend to agree with most everything stated here. Nothing wrong with wanting to get the best mileage possible with your rig of choice. Has a lot to do with the tow vehicle and the height of your coach. If you get real good mileage towing, you're likely not driving much of a vehicle or towing much of a trailer....not a problem if that's what you like. My wife and I don't tow to save money traveling and we never tried to figure out if it's the most economical way to travel............likely it's not since we just spent $80k on our set up and I could have flown a lot of places and stayed in some nice resorts for that kind of cash. We just like road tripping with our trailer, stopping to make sandwiches for lunch when we want etc. If you buy a gasser, it will likely get the same mileage as a diesel when they are unloaded cruising down the highway. Put a load on it and you seem to get 2-3 mpg less. What I like about my diesel is going up hills at 70 mph and the engine is only turning 1600 rpms. Yup the cash out-lay is substantially more and I will likely not see a dime of that out-lay returned to me due to better mileage or less maintenance..............and I don't care. It goes up and down the hills super easy pulling my 6000 pound-ish trailer and that's what I like. I get anywhere from 11 to 13 mpg pulling on the hiway with average hills. Throw a headwind into the mix and I drop to 9 mpg, but the truck doesn't slow down a bit, just uses more fuel. A gasser will have higher rpms at the same speed up hills of any size. It's just a matter of what you can afford and/or what your personal style or personality will allow
