cheers guys, I have tried a few places windsheild, bonnet (hood) and along the side of the truck. Infact the shell is starting to look like a tea bag.
you may be onto something squee, as all the locations Ive tried are up front near the raidio box and ubec. I will try the rear of the shell next week and see if it works any better.
Failing that I could tie it on a peice of string and tow it behind me :032:
