Assuming that the craft had to sit vertically, with all 5 wheels on the ground (which I think is safe, the CG looks like it would be fairly high and tipover must have been a concern) then all 5 wheels would need vertical travel in order to absorb the shock of landing and keep it upright over a range of gross weights.I think that the outrigger wheels woul have just a telescopic hydrolic piston for retrac it....and no suspension...it's clear on blue print...
