I like this mod a LOT.
wvabeer, I have a few questions, now that you've had yours finished for a while.
1: What are the dimensions between the upright panels/seat backs?
2: What are the dimensions between the lower panels of the boxes?
3: What would you do differently?
4: What would you do the same?
Everyone has their own ideas of what works best for them. I like the idea of tilted seat backs for comfort. I also like the idea of moving the table post out as far as possible for stability when going up to or down from the cabover.
