I debated long on the MorRyde and Torklift steps with a concern to access of installing the MorRydes when you can’t extend them. Last summer we were in a site that was very narrow and I doubt the MorRydes would have worked. It sold me on the Torklifts which I installed. A month ago where we store the fifth wheel, the boat in the space next to us was parked just on the other side of the space line which impeded fulling extending the Torklifts. No problem, I could pulled them as far as possible and set them up, then safely went about getting in and out. We wanted to go from a 3 Step to 4 when changing the steps and have a more solid step. I’m doubtful a OEM type of 4 Step unit would fulling extend with the boat so close next to us.
