Physics is better than brute strength as I have come to realize in my 50’s. 20’s and 30’s I would have loaded it on my back today not so much.
It is pretty doggone big - 4.5 ft X 4 ft tall x 2 ft deep, and no really good places to grab on the back. The back panel is not structural. But once I leveraged it up and got that dolly under it, it was smooth sailing.
I ended up centering the dolly (or close to center) and it turned out that there was just enough clearance so that it would roll without dragging on the carpet.
Anyway - keeping busy while I watch the election returns. Or wait for them.
