WORD!
I want to go hog wild on this thing. 1.5" .083 4130 for the lower frame rails and main hoop. then 1.5" .065 for the rest of the frame, and 1" .065 for all the triangulated structures. Going for LIGHT weight, and still jump a house.
many turnkey kits with all 1.5" .083 DOM weight in around 900lbs. If I can get it lower than that I will be happy.
