I went and looked at the bed last night. It's in OK shape. Lots of dings. Minimal rust, appears to be surface only. The corners are pretty beat up with one being split. The left dually fender is in really nice shape, the left side has 2 cracks. I can send pics if anyone is interested. It has a good tailgate and bedliner. It has a camper shell top but it's pretty rough looking.
But, he does have a really nice 92 w350 dually LE exteneded cab 5 speed for sale. Freshly painted (chassis too) with new tires and alloy wheels. 175K miles. He's looking for $9K. If I had the cash I'd have bought it on the spot. If anyone is interested PM me and I'll give you the contact information.
