I never seem to do well with ramps, which is why I have tried the Milenco Wind up, ( and it was a windup, Im sure), the Lock n Level, and the Fiamma Yellows, but I always feet the van is trying to twist the floor in the way that I always end up with a creaky floor. Not so much with this van as the floor is a different composition altogether. It does seem to me though that the van always sits better on flat boards.
As we mainly use club sites, there is usually very little levelling needed and for us, a couple of boards suffices. The boards are lighter than even the Fiamma Ramps, I thought the Lock N Level quite heavy and the Milenco too bulky. As we are, or at least most of us are going back to steel gas bottles, the less weight in the locker is to be desired.
I have to say I wouldnt want all the faff with a twin axle for levelling and wheel locks.
