Dodge RV... what's it worth?

I've been actually looking at these things lately, just because they....are....so....ridiculously.....CHEAP!!! But as Zhandfull mentioned, you've gotta watch the roofs for leaks and interior damage. But yeah....uhhm...I'd guess that one's worth about $2250~$2500. I am looking for a Dreamer or a Lazy Daze (all aluminum riveted camper section with a Dodge van front with a 440) Even the nice ones can barely fetch $3500.

Here's one I've got my eye on....check out that price, and the dude said it was a 440.
