Yep - a few people will raise concerns about the propane running while on he road. Most of us, however, run the fridge while on the road.
There is a lot of good advice on here, but the one I will echo is to ask for help! If you don't know, don't guess. There are plenty of us that have been there, and we're more than happy to help others. We started, 3 years ago, with absolutely no experience. I spend many hours on this forum and learn a ton from people here and elsewhere. It will be a LONG time before I'm a veteran RV'er, but I'm light-years ahead of where I was because of those willing to help!
