I am missing 1 measurement for my window choice. It is the space between the stamped cutout for the windows and the metal rib. I have attached a picture that outlines the measurement I need. Ideally on the 4 sides (up center /*down center /*right center /*left center). If someone without insulation /*wall panel could take this measure for me it would be very nice! I will have a 3500 extended but I'm guessing it would be the same for a 2500 as well !
That measurement appears to be the width of the metal seam? It is approximately 1/2” to 3/4”, but not consistent.
DO NOT order windows based on photos, other people's measurements, etc., unless you are ordering from a company that guarantees them to fit or ordering something obviously smaller than the space available. If this dimension is critical to your decision, you are cutting it too close.
Wouldn't the dimensions of the opening (not covered by structure) be more appropriate? Which windows are you considering?
All the best,
Yes it is an important measurement as for sizing the windows. But the measure I was asking seems to be important as well, at least for the tern overland windows where you need to have enough clearance for the window and van body to conform together.
I have received my promaster since this post so I can now do my own measurements and finally start installing stuff!
Good to hear. We have considered making inside spacers to conform to the undulating surface of the lip so that clamp ring seats better. Let me know if that can help you with the Tern Overland install. We made some very thin adapters for the outside of a Sprinter for a builder who was installing Seitz windows. The strips accommodated the curvature of the van skin and provided a flat surface for the window frame. This kept the window from distorting the sheetmetal.
