Having recently aquired 2 MAX units at work, we in the fleet division have gotten intimately familiar with the innards of the MAX. Even went to the factory, as it is here in Buffalo. 21 grease fittings. 21! And about 129 other things that need periodic tweeking and twisting to make sure they are perfect. Granted, we're picky.
I agree about the ride. Way to rough for my taste on hard ground. I managed to high center one on a snow pile. Not much ground clearance on the belly.
Ours idle fine, plenty of power. Deep powder snow bogs them down some, but they keep going OK. One bent wheel is all we've replaced so far (so good).
