I would be very careful about putting that much weight on that thin wall tubing.. I have 2 of those type frames and both
have collapsed just from rain water collecting in the trap.
The lean to with the right support would be better..
Good to see or recovering from the surgery.
Yep, been thinking about that since last night. The 1.25" round tubing strength from the tarp shelter is far less than the original 2.25" square tubing used to support the 9' long x 36" wide steel panels. We measured the wall thickness of the round tubing at 0.032" and the wall thickness of the square tubing at 0.088", a substantial difference. And the square stuff is construction grade galvanized steel, not low strength steel like the round tubes.
Plus, the design of the garage uses the square tubing spaced about every 4.5 feet apart. If I use the round tubing, I could potentially have a 9 foot long run with no support underneath which is simply not strong enough to support the panels. Adding additional supports at shorter distances may be feasible but I need to check further.
And the uprights would have to be extended on the off wall side of the lean-to. Taller means weaker. Might be able to do something with a wood post but that is still TBD.
Research continues...
I found some pix online of similar ideas.
This lean-to uses what appears to be paneling identical to my own. Note the beefy square tubing, corner bracing and the "correct" roof brackets.
Another similar lean-to using steel tubing as well as some wood.
