Just picking up on this thread, I guess the wheelbase of the 3wheeler is 2014mm.
Pity it wouldn't fit into a large van. We have just spent 2 weeks in the South of France ( Dordogne) where motor cycles have a large presence, it would of been nice to ride around in a 3wheeler (misses will not do M/CS).
PS:- the Van would be towing the Caravan.
