You will rarely find a CG site that is perfect level, perfect height to use the RV steps comfortably.
Most carry a lightweight plastic 'two' step stool with to use 'instead' of the RV steps. (actually makes it easier on the knees to go up and down on)
I've tried them all and this is the one that works the best for me almost all the time. Fits nice and snug up against under the door. So much so that I completely 'stopped using the RV steps' years ago! :B
I also use it inside the MH to access the cab over works perfectly. Comes in white also. Ace Hardware usually carries this one.
