Last week I pulled this Rheem, propane, updraft gas furnace out of the new house. I installed a new electric unit. This unit is in very good shape and should work just fine. This is minimal surface rust to the heat exchangers.
You could probably hook up a small propane tank and use it in your shop or hunting lease. Would also work great in your house/rent house.
It is free of charge to any Pelican that would like it for this winter season. If no one responds prior to the 19th, I will probably sell it on Craigslist.
Oh, and no shipping lol, you have to come get this baby!
