I can't just stand up and walk around in the Rolling Steel Tent. The roof is too low. Moving from one end of the van to the other is often a matter of butt scooting. Hauling myself up out of bed and into a bent-at-the-waist stance can be a bit of gymnastics. (And he sticks the landing!)
My van life is made much easier by a couple of grab handles. The all-steel contractor cabinet, which is bolted to the wall and through the floor, is a great attachment place.
