Any tips on installing a track system on a T1N? We have a 118" standard roof. I am heading to a local wrecking yard to pull a few parts including a set of the roof rails from a 2008 Sprinter.
If you're going to be installing used roof tracks be sure to fully inspect them, especially if you weren't the one removing them. If you are removing be careful to not bend/crease them, they're just aluminum.
For installing those tracks on a t1n it will be pretty custom, might have to cut them to the length you want which isn't a big deal. I can't remember how the ribbing looks on top, but you could cut the tracks and do two separate sections of you need to span over any ribbing.
Whether you're doing riv-nuts or plus-nuts I make sure you have a proper tool and know how to use it. They can be a pain to remove if not seated or tightened correctly. Check your spacing between riv-nut or plus-nut and the bottom of the tracks, might want to put nylon spacers or washers to fill the void if there is one. Be sure to silicone everything. Try to reuse or create your own end cap for the tracks on the front edge or you might get a whistling while driving.
Since you have a short roof if you're just looking for crossbars your easiest set up would be rain gutter mounted towers (Yakima 1a or Thule 300).
Good luck and let me know if there's anything else you need
