We cheat, but we stay in one place for months...
Our original OEM DRV steps from 2010.
Still have those, but because we stay long term, we now have these as well.
Those are made with four sections. These stack upon each other, and to prevent slipping, we put brackets on the inside and round steel rods go through those brackets to prevent the sections from moving around. You can see the brackets in the second photo below.
When we do move, the two middle sections are the exact same length as the top and bottom (shortest and longest) sections, so we can put the two middle ones on the top and bottom ones in our Ford Expedition Max to haul them to our next place to live.
