We've pulled a trailer to FL several times. Be prepared to pull over at the first sign of a storm (bring a Walmart map with you..most welcome us, as long as we don't pull out the awning, and take advantage). I suggest you keep it winterized until you are well away from the cold and don't be fooled when you come back, into not winterizing until you get home..be sure you do it before you get to the cold. Those little pipes freeze easily in the walls.
You'll love your new trailer! We have a Holiday Rambler (it's about 30.5 feet) and it's our first with a slide. We've had it 3 years already, and I'm still amazed at the room inside. We camped this past week with 3 grands and lots and lots of stuff (just how long did the parents think we were going to keep them LOL?) and it was so hot (as you know) here in NYS, that we had them stay inside and play in the midafternoon, and there was plenty of floor space for a couple of games, as well as the table and couch for the "ol folks". We've tented, and had several trailers, and each one has brought immeasureable joy! It was a real bonding time with our children, and continues to be with our grands.
