I bought new steps from my selling dealer when I bought my rig, threw them in the bed of my TV, brought them home, and I installed them myself in about 45 minutes...including digesting the instructions. I installed them before the rig's maiden voyage. The factory steps are still brand new...and available to anyone who wants them.
One caution on this style of steps. The side rails make "great" slides. If you step on the side rail instead of the step, you'll be on the ground before you know it! Ask me how I know...
Why would that happen? New rigs have friction doors, and it's not uncommon for one to not open the door widely enough to have a clear shot at the steps...and place your foot on the side rail instead of the step.
The second issue with these stow-inside steps is that they can pose a problem if you are parked in tight quarters...maybe at a storage site. Not an issue for me. I park in my driveway at home.
Third, in the rare event where you setup on a site where the curb side is higher than the road side of your rig, these steps might be too long and require digging a hole for the feet. I've done this once in two years. On that site, I had to setup "backwards"...with the curb side facing away from the lake. No big deal. "Improved sites with "paved" pads don't have such problems. I carry a pick-mattock
with me at all times to "improve" primitive sites...such as digging a hole for the uphill (road side) tires on significant lake-side side-slopes...to aid with leveling.
But with those provisos, I wouldn't trade mine for the TorkLifts for two reasons.
1) I boondock exclusively, and this means going down ATV trails and over rough terrain full of whoop-de-doos and over ridges. My steps stow inside and don't eat up ground clearance. TorkLifts hang down under the rig. My factory steps hung down in harm's way, and on my previous rig, I had to carry a sledge hammer to straighten them out after grounding them on the way to and from chosen sites. (Photo) In fairness, the TorkLifts don't hang down as far as the factory steps on my old PUP, but you get the idea.
2) The TorkLift's MANY articulation points are an issue if you travel on muddy or dusty roads. Far too much "monkey motion" for me. If you go off the beaten track, anything with all those scissors joints will need regular cleaning and lubrication. My steps store 100% inside the rig, and they stay clean. But that's a preference... If you only go to RV parks, all those exposed "hinges" won't get clogged up with grit quite as much.
For those who gripe about the swing up steps carrying and dumping a lot of dirt inside the rig, ever heard of a whisk broom? Two seasons of boondocking every weekend on often unimproved sites, and dumping dirt inside is just not a thing. I sweep the steps before I fold them.
Those are my thoughts...worth every penny you paid for them.
