Well the unit is really well built, we have only 2 issues and one being the slide in for the main area leaks a little in a bad storm but only when it's already pulled in....still scratching my head on this one... And the other is an ongoing gas alarm that goes off with no gas on.... Despite having a new battery for the camper all is well. I want to add the flush system for the rear extra tank.... Your right I have found almost nobody with our units. But I can tell you if you ever decide to sell, these units go fast and for good money! Seems like your 6.7 should pull it very easily! I think if Ford or another manufacture would bring in a 5.0 or larger with the ecoboost they will have a winner. I have shied away from diesel just because of the crazy repair bills if anything goes south. They are awesome pullers though! Let me know if your camper has the same issues, you have the new color scheme which I like better then mine btw.
