My propane tank is just set on some concrete blocks, they almost look like parking blocks. My shop still has a propane tank but my house is geothermal. We used to have a tank at the house near a downhill area. It got out of kilter and looked like someday it would head downhill. I just pulled it level with a come along and shimmed it up. It lasted for years like that.
I just read this thread from start to end. Not everyone’s posts but I mainly read the OP’s posts, watched a few minutes of his videos. I’m sorry, it’s not a very good story, not even a good adventure, but it definitely qualifies as an excellent saga.
Whew, best of luck in the continuing saga and for Pete’s sake, move in and enjoy it soon!
