Thanks for the input. I like the 3 wheel dollies. You are correct, too many projects, 24x36 space, two cars, a dragster, 1 bike down, 1 on a shelf, 1 on the wall, one on the H/F lift and the old wooden door bike platform is still here.
I bought 2 of the 1,000 pound furniture dollies and put them under the rear wheels of my 1,800 pound dragster. I figure 75% on the rear wheels so 650-700 on each cart. no worries.
I rolled it out of the trailer, spun it 95* and right into the shop. Until it ran over the expansion joint crack, "ping" bearings everywhere. LOL. I just got a spare one last trip. Much easier than a 24 point turn with a 235" wheelbase.
