Hey there and welcome to the forum! It's awesome to have someone with insider knowledge about the Nissan plant in Smyrna join us. Your experience adds a unique perspective to discussions about trucks and modifications. As for your Pathfinder, upgrading it for more capability sounds like an exciting project. While a 4WD conversion might be challenging, there are plenty of other options to enhance off-road performance like the off-road bumper, rear bumper, fender guards, high speed internet providers and skid plate you mentioned. Can't wait to hear recommendations from fellow enthusiasts on suspension kits and tires!
