Mobility scooter ramps

[Phil Hall]

There are plenty of threads on mobility scooters towing and on racks but I cannot find anything on putting a mobility scooter in the rear. If there is apologies.
I can get it in nicely in the rear with the rear bed flipped up but I was looking at various ramps on the market to make it easier to wheel up into the rear. Has anybody done anything in this area?
