Although I don't own a Jayco, it was the Jayco Eagle 29.5RKS parked next to us at a campground that eventually changed us from a TT to a 5th wheel. And if we ever full-time, I am thinking the Jayco Pinnacle line would be our first choice. So with our 2003 Tundra barely adequate for our 5500 lb TT, a brand new 2011 F150 5.0L V8 camped next to us with the Eagle 29.5RKS. They gave us a tour of their Jayco and we loved the floor plan. They had just picked it up from the dealer and were on their maiden voyage. He had added air bags and said it towed great.
I had already planned to trade up to an F150 and research indicated the couple was very over loaded, but the F150 could be configured for appropriate 5th wheel towing. A few months later, I picked up an F150 EcoBoost with Max Tow. Although I wanted the HD payload package, it was only available in the 6.5' bed which would not fit in my garage, so I ruled it out and added SuperSprings and the HD payload shocks which improves the capabilities, but not the payload sticker. The specs of the 29.5RKS were studied and I was put off by the 1700 lb pin weight, but the DW insisted. Dealer issues started us looking elsewhere and we found a Cougar High Country 299RKS with the same floor plan and 300 lbs less pin weight. We absolutely love both the towing and camping experience of a fiver and put 3000 miles on it last summer with plans for 8-10000 miles this coming summer.
