Haven’t pulled it anywhere much since I bought them both. Lived in the camper while waiting to get in a new house. Pulling it home on the interstate in hills and trying to keep speed about 65, the rpms were very high and I was concerned. Also, dropped to 7 mpg as long as I was in hills but mpg isn’t a major factor. Performance on the road is more important. Downsizing for traveling and want to make the right choice.Buying a tow vehicle questionNew to this website and new to rv’ing. I’m wanting to buy a tow vehicle for a 20ft tt with about 3800 lbs dry. I would like to buy a 1/2 ton as it will be used as a family vehicle most of the time. My wife and I will be towing a few weeks out of the year all over the US, including mountains. Looking at f150 with 5.0, Chevy 5.3, and dodge 5.7 hemi. Would like to be able to maintain good hwy speed in hills without a screaming engine. Any suggestions about truck and what axle ratio?
