Wow! Thank you to all the responses. My husband can't believe all the help we receive here! : )
I have the 3.73 ratio rear axle with a tow package.
So this weekend we looked at a few things. We have kind of decided that we should not do any hybrids because my husband is interested in going to Havasu in Arizona in the summer. So tent siding would be hot. I will research good TT for insulation. The RV salesman highly suggested the Passport Ultralites. He said they also have amazing insulation. We shall keep shopping!
Thanks again everybody!
