I own a business that requires me to travel around the country in the summer vending at homeschooling conventions. This year, I want to take my wife and four daughters (aged 8-13) on the road with me for two months, June and July. We are on the East Coast and will follow the convention trail to California and back. I'm thinking the best route is to buy a used RV and resell it when we get back (this will be a one-time trip). Renting seems ridiculously expensive. I just attended an RV show in town and think I need a large Class C or a modest Class A. I'm looking for all the advice I can get, but here are a few questions: Do I want diesel (I hear their resale value is better)? Do I want to go through a dealer or search for private sellers? Will I need a CDL? Are there certain makes/models/years that would come more highly recommended than others? I don't know what my price range is yet, but let's assume price isn't an object. What's most important to me is that I can recoup as much as possible of my initial outlay when I resell it 10 weeks and 12,000 miles later. Looking forward to your input!
