Twin axle motor mover

I am thinking about getting a motor mover for my twin axle Elddis Odysey  to get it into my garden. It's going to be quite a tight space and will involve a 45degrees turn. I was going to block pave the area toturn on but just having returned from a CC site having been on a gravel hard standing pitch I am wondering if the turning will be better suited to a gravel type surface. Will a turn with the mover be made easier and tighter on gravel than block paving or does it mat make much difference?
