Home fabbed lid, with home fabbed cross bars made from Uni-strut.
Mounted the tent so the lid opens even with the tent open.
Just make sure the wife isn't taking a nap before you open the lid:elkgrin:
I used a set of gas struts, the biggest I could find at the local auto parts store. When the tent is open, the struts will lift the lid by themselves, with the tent closed, they make opening it a 'one handed' job.
