I would really like to find a good deal on a used diesel rv. I'll never afford a pusher, but pullers and class Cs seem to sell at lower prices. I'm looking for a really good deal on something from the late eighties. Craigslist mostly has bad homemade bus conversions and the local paper has no useful information. the rigs on eBay seem to be selling at ABOVE book value. What sites should I look at for an older RV?
