Whether you have an Aluminess roof rack or just a simple storage box, the Promaster roofs are a great place to store bulky things. The problem is how you get up there to strap everything down. Aluminess solves this problem with their all-aluminum rear door ladder. This item bolts into the factory door hinge locations, No Drilling Required! Also included is a limiting strap so the door can stop and not make contact with the side of the van. When you order our ladder/combo kit you will be able to mount one of our storage boxes or your spare tire to the ladder. You will receive clamp-on posts to support the tire or box, a tire mount, and three auxiliary steps to make it easy and comfortable to climb past your tire/box and get to your roof.
