I've sold big ticket items on eBay. I've only had trouble with one person as a buyer.... the items did not match the description. Now, I use an escrow service for big items. I shipped a big digitizer ($2000.00 +) to Canada with no problems /forums/images/graemlins/grin.gif
I love browsing the RV section, I would just bid on listings in my area so I could go inspect them if it was for more than a few thousand $$$$'s. Cars, Trucks, RV's, tractors, I look at in person before bidding unless they have a satisfaction policy which many dealers do have. As stated before, there are many no-reserve auctions. Mostly older stuff, of low value anyway. If the price is to good to be true, be very carefull and don't pay by cash/check. Use a payment service or credit card even on big items and you will be protected most of the time. Or, go and look at it first. I've bought and sold over 600 (seller most of the time) items on eBay, I've been taken once. But I'm a carefull powerseller.
