I had wondered why there was a 1.2m limit. Doesn't seem much for a vehicle the size of a square cab mog.
What's the wading depth of a standard U900? And what needs to be done to increase it? First on my list will be a new filler cap and tank breather - mine are pretty messed up! The breather from the torque tube is present, and I understand the hubs breathe through that section too?
