Either way although if you reverse up hill then your coupling head will be compressed and will spring out when you unhitch.
You then need to move the car quite quickly before it damages your bumper

The choice is yours how you do it but I always pull the caravan up because the caravan brakes have an over ride system which stops the brakes activating when reversing. This in turn is activated by the compression of the damper which then doesn't effectively allow the handbrake to apply the brakes fully, therefore by having the damper pulled forward it deactivates the over ride and allows the handbrake to fully operate. I also do it for safety reasons too because even though I chock the wheel with the correspond ramp chock, if the caravan should accidentally roll away for any reason I know that a yank on the handbrake should immediately stop the caravan in it's tracks but if the over ride is activated then I have much less control.
Most obvious answer is aim to put the leveller below fbe wheel on the downslope and move the caravan that way unless the pitch layout makes it impossible.
