I have a 2012 NV3500HD Passenger that I picked up about 2 years ago since my wife and I saw it as a good option for our youngest child with disabilities and have 3 other kids and a dog. Since owning it, I have installed a 7" in dash screen with GPS, rear view camera to work with it, flip down screen for the kids, rear entry wheel chair lift and Class 3 hitch receiver and wiring for the trailer lighting. There's other little things in the van that I've done, like mounting for oxygen bottles and tie-downs for my daughter's power chair, and also a 3KW inverter for her equipment. I do have the 4.0L V6 under the hood and I'm looking into whether or not it would be worth it to tweak the motor for better performance and torque or swap it out for the 5.6L V8? Also looking to see if anybody has done anything in ways of modifying their suspension as well, I understand that most of the parts are shared with the Titan as well.
