Sprinter Van Side Ladder | Wheel WrapRoof access that actually fits your van. Standard side ladders fight your wheel well. This one was built around it. The Whitetop Adventures Wheel Well Notch Ladder features a contoured lower section that wraps clean around your Sprinter's rear wheel arch letting you mount the ladder further back, right where it belongs. No gap between you and the van. No awkward first step. Just a solid, straight climb from the ground to your rooftop. Why this ladder.
