I just purchased a 2018 6.0 off road edition. Actually bought it on the way to go camping, somewhat on a whim, and just got back with it. All in all I enjoyed my weekend not having to crawl around in a tent and sleeping on the ground. When I got back I decided to crawl under the camper and have a look around, curious about the floor primarily. I found 2 cable clamps just hanging on to the cable bundles and a hole where a screw was holding each of them to the floor at one time. This is a little disconcerting to say the least. All the other clamps appear to be securely fastened, but my spidey sense tells me there are going to be further problems here. The composite floor just doesn't (in my opinion) have the structural capability to keep screws secured that are under stress like those ones are. I sent a request via my dealers website to contact me regarding it and I just received an email (Sunday, btw) from the owner that they will call me tomorrow. I have a few other issues but this is the biggest one for me. Stay tuned.
p.s. I actually don't mind the composite floor, it seems sturdy to walk on. Time will tell.
