Sorry for the lack of response as we went camping...
The idea on saving money with a TT is both to stop renting now and focusing money towards debts and savings for a home. The idea of using the trailer instead of a hotel (Marriott is typical) was secondary.
SWMBO is allergic to most pets and all family have them. We stay up to a month a year, but we'd travel more if we had a TT, especially with internet/cell service.
I have a 2003 F-150 with the 5.4 with very low miles. Figuring I'd add a chip to help with output.
Options are somewhat open but have predominately considered staying here in Texas where we are (near Austin) or going back to SWMBO's hometown of Kansas City.
A lot to consider, and I'll take a look at the expenses of minimal to exceptional solar panel needs. Enough to power everything but the A/C might be more reasonable, especially with power hookups.
'Tis true I am ignorant about TT's as well as solar.
