Every so often we park at a place that the front of the rig is
higher than the back, by a lot sometimes. Because of Mary's arthritis
problems can have trouble getting up on the first step. We found
this at Camping World. It makes a really great first step/platform
to get into the rig as the size allows both feet on the step at
the same time.
As you can see in the right side image, it folds up and stores
in a very small space. Just another goodie to make "camping"
more comfortable.
