Really wheelbase depends on a lot of things such as how you wheel, size tires and also moving them away from the tub will give u a better approach and departure angle for climbing steeper stuff without anything getting in the way.
I did see where wheelbase helped out with the Resq1 rig climbing that steep hill (PNW series I think), other than that I guess I hadn't given it much thought.
