There is one teak roof beam 12" x 3" about 17 feet long across the garage (about 16' wide and 25' long) but it has a scarf joint at the mid-point (two pieces of demolition timber from a shop I knocked down) and has already settled a bit, I have used the builder for years and this would not be the first roof to come down that he has built or the first Jeep I have dug back out (but he is very cheap). The other roof timbers are.... slight shall we say. The whole garage cost $3000 including custom folding doors, bathroom and sleeping accommodation for 6 so I should not complain.
I think a frame will be needed but the straps sound simple, with multiple attachments.

With a Jeep every prayer counts.
