We received our new GlowSteps today and I installed them no problem. They suggested we get the 25 1/2" wide model with spacers but based on others' experience of installing the 27 1/2" model (i.e. Lou Dick), we decided to go with the wider set. They were a perfect fit. As with Lou's installation experience, I had to coerce the brackets just a little and the step frame slid right up into place. The outside width of the Torklift 27 1/2" frame is exactly 27 3/8", so plan accordingly if you order a set.
It's nice that they suggest you remove the step assembly from the frame before installation. Working with the empty frame was much easier than trying to wrangle the entire assembly while tightening bolts. I did have to notch the J-wrap on one side to gain a little clearance for the moving portion of the steps since our step brackets were not perfectly centered in the opening. Our son was up for a visit and helped me with re-installing the step assembly into the mounted frame. Otherwise, I was able to perform the entire installation unaided.

Steps deployed. The ground at this site is a couple inches lower than the pad. The steps are on the medium setting and the legs are at the next to last adjustment setting.
So far we are liking them. Of course, tomorrow we fly out west for the holidays, so we won't get much practical experience until January when we get back and start traveling in Florida.
