I have installed kitchen cabinets for many years and made jacks to hold and level the uppers before screwing them on the wall. I made a tiny cabinet jack the is adjustable for our fifthwheel step for the reason the OP wanted. Nice to not feel people going down as it feels like an elephant is going down. so just one on the bottom step on the side of the hand rail works great. Our steps are not the wimpy steps of todays rv's so it was not the reason for doing. I have made many and take 2 with us each winter for anybody that needs a solid step. Easy to make and not better than products on the market but nice to do what a guy can do. I would send a picture but never got the hang of doing pictures on rv.net. So the answer to the OP is YES.
