How it’s meant to work: tip tray high (beware power lines etc…) to drop the rear edge, then drive
the vehicle forward onto the ramp(s), then lower the tray to align with the ramp. Click “Auto” to align the
tray & ramp(s) automatically. If the weight is a factor, lowering the tray will make it easier but watch
the belly clearance.

Geometry only — also check the ramp load rating against the loaded vehicle weight, and that the winch/crane can hold the vehicle on the chosen tilt while driving or winching up.
Note: assumes the real pivot sits level with the tray surface — true position unknown, close enough for this purpose.
