NOt CL, but has a BIN on ebay, so thought I'd share - don't see many of 68 Custom Campers
with original 396/TH400 (but I'd confirm that originality before buying - it was at least born with both). Seller seems to not know much about the truck - could not identify TH400 (and probably a lot of folks can't) and also has a total of zero feedback, so might be something to consider - good candidate to see in person, that's what I'd want to do (if you blow up the first pic, you can see the telephone number...
). Camper comes with it, although it's not exactly period correct. Nice old truck. $6800 BIN probably isn't out of the ballpark on it - but it does have some rocker rot. Anyway, love the custom campers... enjoy.
