IMO, I'd mount the shocks outboard more both top and bottom.. you've got tons of room, and it would help free up some precious interior space.
Also, to get the most fuel out of the tanks, they should point front to back (valves up front), and be at least horizontal, if not slightly tipped valve end up (but since we hardly ever operate on flat ground, that's not vital IMO.)
It'll also be easer to remove them if they are front-to-back. 
Awesome to see more progress!
