I've got a Powrtouch mover fitted to the front pair of wheels on my twin-axle Heritage. Does a good job - as you definitely will never move a twin-axle by hand! however, be aware that turning a twin-axle will still be a slower process than a single (you'll never 'spin' it!). I don't think lifting one pair of wheels off the ground is very viable - you could end up with a very strained jockey shaft/bracket as there is a lot of weight on the front chassis of vans this size. If the shaft bends while your nose is up, you could have a problem as the wheel may not wind down again? Maybe someone with experience of a mover fitted to the rear wheels may be able to offer advice? In conclusion, I definitely endorse the usefulness of a mover on a large van, it will get you in and out of difficult/tight situations, but don;t expect miracles....you should really be able to do most of the manouvering with the car!!
