I have dug a 2"deep, rectangular trench to inset my base, which is joined. The PVC should be able to stand up to drive-over, when it's snug in the trench. My roof will be made of 45° couplings joined to 8.5' 2" PVC. The rise comes out to about six feet. I may splice in 4-way T's mid roof, to add cross pieces for strength, with 3-way T's on the perimeters. I am building the roof, first, on the ground, to see if I'll need the cross pieces. The roof, itself, will have tarps over it, held very tightly by adjustable cordage. The complete structure may be guyed, at its corners and mid sections. I'll see how sturdy it feels, once completed.
