The cost of RVing is contingent on your priorities. If you want to live in the lap of luxury, stay at upscale RV parks and resorts, and eat out on a regular basis, the cost will be pretty high. If you want to visit New York, Miami, Los Angeles and other cities with major attractions, an RV park with close proximity will be pretty expensive. On the other hand, if you want to see the country and are happy making most of your meals, the cost will be significantly less. Choosing an RV is no different. If you want a newer high end diesel, you're going to spend a lot more than you will on an older entry level gasser. You have more risk with the older RV, but you also have more money to have them fixed. Whether they're new or used, they're going to require maintenance. Tires, batteries, engine and generator service, roof sealing etc., etc., etc. The list goes on and on. Depending on your time frame, do as much research as possible. Ask a ton of questions. Great resource here at the RV Forum. There's never been a question that wasn't answered. And in my opinion, with enough responses, you'll get enough information to make an informed decision. Good luck.
