My other fine cutting tool called a chainsaw really helped me out. The roof went on with only two paper like cuts on my hands. I built the roof from standing on the inside of the structure. Thus, If I fell, I would go straight down, not impailing myself on all the stumps by the sides.
I am almost done now. I need to get the ridge vents attached somehow. I may need to straddle the roof. I may ask for some help. The suffets, I may do in plastic. I need to go visit the depot again this w/e.
Mike, if it were me, I'd jack it up to take the weight off that wheel, remove the valve core to let all the air out, pull that piece of tree out, clean the tire bead and wheel rim good, and air it back up, but . . . . I don't know whether you have a jack, air compressor, tire gauge, valve tool to remove the core, etc. or not.
