Had two safe companies turn me down. They don't have the staff to do moves.
About 60 miles between locations.
I can get a 1500lb rated, power stair climber for $150/day from sunbelt. 3/4 ply is $60 a sheet at Lowes...
Yeah, down side of high end security is increased weight. I could pull the fireboard out but that's not going to make much difference and will just mess up the interior.
Stair climber and a ramped trailer is what I'm thinking. Probably use a come along as a belay line.
