Ahhhhhh, just about done!
Tonight I sandwiched the front and sides of the lid between the piano hinge and a 3" flat aluminum bar to tighten things up. Very happy with the results. On the sides I used left over airline tracks.
I made sure I could open the tailgate with the lid closed...
Felix, unless you came helping me paint the lid you don't get to comment on the color! Funny I don't remember you helping... ;-) I secured the tent via the supplied tracks directly to the roof of the lid, very secure that way.
Still have to fit struts and some electrical until I can call it a day!
Cheers
Mr. D
