We have a 6 point level system. Back in, chock all wheels, hit auto level and 70 seconds later the 5er is level. On severely uneven sites I peek at the bubble gauge I have mounted on the pin. For every mark the bubble is off to one side, that side is lower by one inch. On those sites that really slope I back the 5er onto one or two 1 1/2" x 12" x 50" planks that I place on the low side. Once level I put X-chocks on both sides.
On departure, remove X-chocks, hook up, perform pull test, remove wheel chocks, and then hit the highway.
