They are putting the 3 track system on all 2014.5 and 2015 units. Unfortunately, this is common in the "production" RV business. They have to cut costs to remain competitive. For me compared to say Jayco, Thor is doing much better at a lower cost. For instance, Thor uses corrugated wire protection and properly zip ties all wires. Everything is neatly laid out and organized. with Jayco they just run the wire as a disorganized mass, no wire protection, undersized wiring, and minimal zip ties. Thor used proper insulation for penetrations, Jayco used little or none. Thor uses cheaper cabinets than Jayco but for me I don't care it is an RV. Jayco adds some bells and whistles that Thor doesn't such as most of their units come with in dash navigation the problem is it is way out of date radio and very expensive and frustrating to update. The bottom line is for what you get Thor has a great value. I really do like their 24*7 customer service never got that with Jayco. Monday - Friday 9 - 5 EST only.
