I decided to fit the top hinge last, using the ramps ment it was easy to pull the top down with ratchet straps, I marked the inside of the long ply sides with masking tape so I could see where the top needed to be pulled down to then used carpet tape to pull it all into line (all single handed) I have lowered the roof once (moment of truth) need to make a slight adjustment to get the front right corner to sit flat and have to take it all apart to move the roof back 8mm, live and learn!
I will definitely have a better idea of what I am doing for the next one!
The ramps have been fantastic only problem is they are needed for something else so I have to be finished ASAP
