Hello, I'm awaiting the delivery of a Nissan NV 2500 Standard Roof this September. I'm looking to use the NV for Dirt Bike hauling (Husqvarna TE300), camping and general outdoor use. Moab trip planned for spring! Question, Does the Titan and NV share the same frame? Can I mount running boards from a Titan on the NV when it arrives? I'm looking at rust proofing options and have read the oil/wax spray is the way to go. Undercoating may in fact trap water against the frame. Suggestions? Thanks so much, Shawn
