Graeme presented the following explanation :
Our garden is on two levels, both of which are paved, with a six inch step
between the two. For various reasons, I have been using a couple of thick
planks, resting on a fence post, to move vehicles and trailers from one level
to the other, but would like to construct something a little more easy to
use, but not permanent.

Could you not just use ready made car ramps, as intended for car
serving and just drive straight off the end onto the higher ground
level?
