I have a lot of questions on Prevos. First, if money isn't an object which are the best models for the last 2-3 years. What options are best and which are to be avoided if any? What would be a high estimate for average annual expenses if I used the coach several months out of the year? Is there an experienced owner out there who is willing to chat on the phone to answer some lengthy questions? I'm trying to get as much research done in a little time before I make a purchase. Any and all information would be much appreciated.
