For Standard Gear, What's your ladder of choice?

The specific reason I wanted it was to be able to more easily clean my windshield. I don’t need it to get on top the RV, as I have a ladder in the rear I can use for that purpose. Besides my goal was to have something as compact and easily storable as possible, and I think this ladder will accomplish that. It’s not like I’m going to be pulling it in and out all the time…r
