Hopefully soon to be 1st timers from the midwest. We're looking at "entry-level" TTs and the heated/insulated underbelly is a rare feature on them. Is it worth it? Does it matter? We're not hoping to camp all winter, but it would be nice to be able to use our trailer when the low at night could drop below freezing. From my research so far it seems like most trailers tend to not make it below 40Â° well regardless, so I'm starting to think it doesn't matter much and I could probably add heat pads and so a little heat tape and insulating myself and be fine. I'm looking for input, so share away. Hope to purchase soon!
