We have stayed on a couple of sites recently where there has been a slope from side to side so have had to use the levelling ramps. I tend to use the mover and go forward to level the van. If I go backwards instead and level the van should I go forward a short distance to fully engage the handbrake.. I have searched and seem unable to get a definitive answer as to whether the handbrake will engage properly if the van is moved backwards. It seems fine when I use the mover to get the van into position in my garden going backwards.
