I attached a new product to the back of the foamboard called trunkliner. This is a soft fabric that is only 10" wide, but it has a self adhesive back, so all I had to do is peel and stick. I did this in case the board would flex and bump the roof, it would not make any noise.
Normally, the idea is to lay the pattern out so that it is about 5" or 6" in from the edge all the way around. Unfortunately, that would not work in this truck, because that would have decreased the headroom even more. I ended up only going in 1 1/2" all the way around. The problem with that is the more vertical it is, the harder it is to get the wrinkles out of the outside edge where the headliner fabric is attached to the truck. The only way to see if there would be more tailoring needed would be to mount the board in the truck and see if I needed to sew in any more seams to take up excess fabric. Luckily, that was not the case, I was able to attach the fabric to the truck without having to sew in extra seams.
No one lives forever, the trick is creating something that will.
