WHEELS WHEELS!!
DM, I agree with your reasoning behind the single wheel but I am aware that the RN need a twin due to the redundancy issue. If one of the tyres deflate whist embarked the ground crew have to repair the cab on the spot thus fouling the deck - not good if you are on a CVS! Twin wheels would allow them to move the cab out of harms way and fix the problem!
Shame this isn't being picked up as part of MCSP, and that WAS due to cost!
