We have a 2010 Jay Feather that we bought in Aug of last year. To date, we have logged 8 trips throught out Central Texas. Each trip averages 3 to 4 days. The only quality issues are the string blinds (quick fix), black water and gray monitors (have never worked properly) and the extremely small space around the bed. My wife loves the kitchen and all of the appliances. If on solid ground the stabilizers work well, otherwise constantly need tightening.
The best upgrade I put on was the Barker VIP 3500 electric tongue jack. Wow, what a convienance package. It fits perfectly. I seached the web and called Vogt, the dealer in Ft Worth and could not get a solid answer as to whether it would fit. I ordered it and took my chances. Bingo, worked.
Now the issue is the amt of toys we try to carry. Bicycles (no bike rack will work). Jayco said no bumper bike rack. Sea Eagle inflatable kayak, 2 sets of golf clubs, TV dish and numerous chairs and rugs. We love our JF.
