Don't know your situation because you didn't say, but you should at least do the math if you are really buying a TT to save money on hotels. Things to consider:
Initial cost of trailer +
Running gear (WD hitch, brake controller, etc.) +
Additional fuel for tow vehicle +
Insurance +
Storage +
Upgrades (solar, electronics, etc.) +
Campground fees +
------------------
= much more expensive than hotels
I agree with the generator idea. Solar is an upgrade if you are an enthusiast and are willing to live with the downsides.
