I was in a very similar situation back in 2007, when I bought a new Nissan Frontier, virtually the same as the ROW Nissan Navara. I'm a long time off-roader, and wanted to start building up my Frontier. I found that very little was available back then (kind of like the current situation with our Twins), but searching the internet, found that ARB had an extensive array of suspension (OME) and protection components for the Navara. I had a long term relationship with ARB, just up the road about 150 miles in Renton, WA, so gave my friend up there a call to ask if they'd be bringing any of it in for our US Frontiers.
Turns out I made my call at just the right time. They were looking for a Frontier, so my truck became a test bed for virtually everything ARB made for the Navara. The process took almost two years, as they started with the OME suspension, then moved to the front and rear bumpers, and eventually the entire line. I am not going to be off-roading my Canyon All Terrain to the degree I used the Nissan, so in spite of some interest in giving it a try, have decided to leave the GMC pretty mild.
If any of you guys are anywhere near Renton, send me a PM, and I'll share my contact info at ARB. You never know, they may be thinking of going after the Twins market. It was well worth the effort back then, and any time they needed my truck for an extended period of time, would furnish me a loaner, so I was never without transportation. Most products were done with 2 to 3 trips to Renton before the final version was ready to install on my truck. Some were virtually an exact match right off the shelf, but some took minor re-engineering. In those cases, I would go up to Renton for the day, while an engineer flown over from Australia would work on the project, then take those digitized drawings, measurements and notes back to Australia where they would build prototypes for later fitment in Renton. It was fun being part of the process, and would try again if I thought my use of the truck would justify it.
Here's a shot of the Nissan with the OME suspension, front and rear bumpers, and skid plate set mostly visible. This was taken during a Warn photo shoot back when they were getting ready to launch the new Zeon series of winches, but early one day before the winch was mounted on my truck. During that 4 day photo shoot in several eastern Oregon locations, Warn only had one prototype winch, and several technicians were constantly moving that solitary winch between about six different vehicles, and it had to work with every move so it functioned in all of the stills and videos.
