There is one out here that fits your bill, It looks like an old bread truck but it is an rv. has a chebby in it dont know what, but would guess a 454 or something along those lines. he wants $2500 or best offer. Dont know where you are located, but look at the craigslist ads around your area for something a little newer. real familiar with the old dodges, but know my BIL had one and changed the engine out. Too many issues and it had all the upgrades like water injection etc. He installed a 4BT in its place.Besides $3500 for something that old and condition is way too much.
