Hi pjesmer,
Welcome to the forum! I don't know anything about buying from ebay but, as Tom said, one should thoroughly check out any RV they plan to purchase. Many times on older models things are not working properly. The selling price might be attractive but you could end up spending a lot in repairs. I'm sure others will know more about the process than I do.
We owned two Bounders when we first started RVing. I liked both of them. One was a '95 gas model and the other was a "96 diesel pusher. I probably would have purchased another Bounder diesel for full timing but they dragged their feet in introducing it so we went with another brand. We now own a 2000 40' American Dream which is our home.
Be sure to ask all your questions. You will get answers. Also, thanks for being out there watching over us so we can sleep easier!!!!
