Just to update on this post: I had some damage to the driver's side hinged step and to the storage compartment door. I ordered the two fiberglass parts new from www.mobiliferv.ca
. The Dupont paint code was stamped on a tag in the van (inside the driver's side door: #B8343), so I had a local body shop prep and paint the parts. I ordered a new plastic hinge for the storage door from Moore Industrial Hardware (https://www.mooreindhardware.com/har...tinuous-hinge/
). I drilled out the rivets to remove the old parts and then installed the new parts. It all looks good, though it was a lot of work! The hardest part was drilling holes into the plastic hinge to match the holes in the van's body without being able to see those holes because they are recessed into the storage compartment!!
The storage compartment door is exactly the same size for the Roadtrek 170 and 190, which was my original question. But the step was shaped differently so I had to attach it using a double hinge so it would sit properly.
