My wife and I have been looking at buying a camper to get our kids into national parks and state parks. We started looking at pop ups, then considered hybrids, and I think, now, we are pretty sure we want a full travel trailer. The pop up will be outgrown with 3 small kids before we get started. The hybrids looked really nice, but I just didn't trust the fold up beds. Even at the dealership, with 2 boys playing and wrestling, it looked like something destined to break with kids. So, we are looking for a TT with a bunkhouse for the whole family. Looking at Great Smoky Mountains National Park (our closest NP), there are numerous "frontcountry" campsites. They have no electrical hookups, some have cold water only. I'm just trying to understand the setup. If no generators are allowed, does that mean no AC at all? Or, do you use batteries for power in that instance? The website says generators only able to be used for a few hours during the day...none overnight. TT's get really hot inside....especially in southern US summers. No way people try to sleep in their fiberglass boxes with no AC. Might as well sleep in a tent....it would be more comfortable. Sorry for the idiotic questions. I'm just new to this and want to know what to expect before jumping in.
