Just installed them this past w/e by myself. Wasn't a too bad of a job overall, but did run into a hiccup. Ours replaced the Lippert 4 step alum fold out ones and getting to the nuts was a bit of a pain, but "got 'em". Tho I had a floor jack and wood underneath them, things didn't go exactly as planned when they came down. Read....CRASH !!!! LOL. All is well tho. The GSR comes apart for 1 person install which makes real easy. Probly the hardest part was holding onto the frame of steps while getting the 1st bolt in. Mind you, shims were sent w/ steps as the steps were narrower than frame. Had to make sure they were where they needed to be as there was no removing them once in place. They have some really GOOD sticky tape on them!!!!! Things were going well until last bolt. Too long as it was hitting some kind of material/plastic. UGH! Off to box store and luckily found a shorter SS bolt. Even w/ the shorter one was still a tad too long, so added some SS washers (main steps and shims both came w/ their own sets of SS hardware), so was able to "scarf" up washers from the steps to add to bolt. Re-attached the steps to frame and WOOLA !!!! Yes they are stiffer to pull/push in/out, but they seem to do the job well as the coach is pretty high/level. 1st trip w/ them is coming up, so will let ya all know how things go.
