1967 3/4 ton Chevrolet pickup with bolt on frame camper

[Sierra72]

Hi, just wondering if anyone has seen or know what a 1967 3/4 ton 2wd Chevrolet pickup with a factory bolt on cabover camper is worth.
It has original 60,000 miles, 3spd standard with 283 4barrel. Cab and front end is in Mint shape, camper/rv needs some tlc, probably has water damage. Original split rims, tires, and hubcaps are still on vehicle. The truck colour is mint green. Talked to the lady that owns it today, husband passed away 3yrs ago, she doesnt know what it is worth.

Anyone has any info or pictures please let me know.

Thanks
