Thanks for the warm welcome fellas
Ill be doing some searching over the next couple days on chassis designs.
On the roof top tent, in the canopy i sunk a platform 150mm from the roof. I have 4 pneumatic actuators to cut down and hose up in each corner. Once hosed up these will provide 870mm of lift, this will be my sleeping area. Will pull up vinyl and fly screen walls to protect from wheather. So sleep up top and have draws, fridge slides, kitchen and shower setup down the bottom
