I know that your caravan should be on a level plan has well has your tow vehicle , I often see caravans that are not is it better to have the tow end dipping down on the tug or the back of the caravan dipping down if you can't get the caravan to sit level .

Brickies - years ago I was involved with this in a regulatory role,,,, remember when you brake,,, the BACK OF THE TOW VEHICLE the TENDENCY IS TO RISE,,,,,,,,,,, AND THE FRONT OF THE CARAVAN TENDS TO DIP.
This way they tend to compensate each other to some extent.
If you have the towbar too high and you jam on the brakes the OPPOSITE COULD OCCUR ,,ie the van could "push" the rear of the towed vehicle up (it could actually reduce the weight on the rear axle in practice) and the combination could become unstable with reduced traction at the rear wheels.
This is the extreme but hopefully you get the idea.
You don't really want the weight OFF the rear axle of the tow vehicle or you could (in extreme cases) increase the risk of jacknifing.
So as a general rule I would suggest if you can't level van,,,, front down is the better of the two evils.
