Wife and I have found the RV we like, (after renting & much searching) it located in Michigan, we're in So.Cal, it's a 25ft class C on Mercedes Benz chassis. Seems like a good deal, its a 2021 with 500 miles, problem being the weather is not on our side to go get it, it's winterized & stored indoor. Question I have is how to check the house plumbing and workings with it being winterized? I was planning on driving it back to LA, and de-winterizing at home. Is it a good idea to purchase a MH during the winter months with these conditions?
