Thank you everyone for the replies - you've given us a lot to think about. In answer to a couple of questions about why we were looking to go from a V8 to a V6, first, our truck is getting up in age & gas mileage is really declining. Second, we're looking to downsize our TT, so we thought maybe a smaller vehicle would also work. Doesn't sound promising, though. We live in the Denver area, so traveling through the mountains is a consideration for us. Sounds like we're probably going to stick with a V8 even if we downsize the TT. Thanks again for all the info.
Most mid-sized SUVs have frontal area restrictions for the 5000+ pound tow ratings. This means not towing a 5000 pound high walled RV.
Power from a naturally aspirated V6 is not likely to be satisfactory for moving 10k pounds, especially at higher altitudes. If you can find something with a turbocharger, you'll be happy. Ford's 2.7L might be a good fit for you.
