Thinking of buying an RV, looking for advice/wisdom

Nocal guy? Buy a used Asian truck and a slide in camper. Use Starbucks, McD's and your cellular plan for the Interweb. This assumes you don't own property to park a trailer when done with your excursion. If you have a home with parking space, trailers make excellent guest quarters.

If you're not afraid to tow with the Audi (why should you be?), a small pop-up or hard-sider is all you need.
