Well, if you're going to be parking it in the garage, your options are definitely limited. If affordability is an issue, you probably won't be able to find a hi-lo either, unless you get lucky with a pre-owned. Those buggers are pretty spensive! After looking at that Avalon, that's a pretty spiffy pop-up. Definitely about as close as you can come space wise to a TT. But being in Northern Maine, I would worry how good a job that fabric covering would do keeping you warm on those chilly nights. To get beyond the claustrophobic feel in a TT, you really need a slide. Even a small slide like mine (just the sofa slides out), makes a world of difference. I mean a world of difference. But the downside, at least in your case, you would have to store it either outside, or somewhere else (RV storage place). Anyway, good luck with your search. It sounds like you're ready to go, you just need something to go in!!
