I snapped a few pics of the details.
Access panels on front fenders.
Underneath covers, you can see red cap on grease zerk and the tensioning setup.
Roller right before landing gear
between landing gear and 5th wheel plate.
You can see both front access plates in this picture as well as the adjustment nuts for the belt. The hydraulic filter is added for the EH controls. They are more sensitive to debris so they add this filter so that you do not have to worry about contaminants from trucks.
Inside one of the access plates.
Belt tension gauge. Keep tension between the fingers. They set it tighter from the factory to allow for initial stretch.
Rear controls, hydraulic and suspension gauges, and rear access panels. You can get in cab variable flow control as well.
Inside the lowest panel, jungle of hoses, upper ones allow access to the rams for door locks and such.
Bumper can be unbolted for bagging if needed.
Knife gate. Has a very thick seal, they said for chopping they tell guys to leave the secondary locks open and the knife gate up an inch or so to preserve the seal.
You can see the secondary locks in the picture. They are what the 4th function is for. You can also see the other door locks as well which are opened when sending hydraulics to the door rams.
Heres a short video of it, not running full speed, maybe 1300rpm on the truck, pump is 30gpm@1600.
