The MORryde # MR73RR is a quick connect step (not fold in) for 21-1/2" entry height and 23-1/2" entry width. Because they rest on the ground they provide a solid footing for steps that don't flex and dramatically reduce trailer roll from users on steps.
If you prefer the quick convenience of fold in steps you should consider the Lippert # LC713662 for entry heights as low as 22" off the ground, and door entry width of 24". If your door is wider there are other sizes. Just email me if... view full answer...
