Jayco Jayco junk sidestep Nationwide

We bought a brand new 2009 Jayco Jayfeather Sport model 226 in 2010 and it had a 2 year warranty on the camper and a 12 year warranty on the roof.  We de-winterized it in May this last spring 2015 and noticed both discoloration in the linoleum and soft flooring at the threshold of the entry door and in the bathroom standing area.  We contacted the dealer we had bought it from and they made an appointment a month out.  The appointment was quick and worthless. They took a look under the threshold to peek under the linoleum and said it is interior water damage; they deducted this because the outside walls showed no signs of delamination.  The service people said they couldn't go on unless I wanted to pay for the repair.  They told me to contact Jayco and see if they would do anything.  I called and the only thing they did was tell me the warranty has expired and sent me a three sentence floor repair procedure (worthless).  

Thinking I might still camp I delayed delving into my Jayco piece of camper until 4 days ago.....  I removed the side panel on the tub, bathroom sink, countertop, bathroom cabinet, and toilet.  I hooked the bathroom sink and drain back up to supply and drain lines.  i filled the water tank and pressurized the whole camper after an hour; no leaks.  I hooked up the city water connection to the hose and pressurized it again after running and stopping the whole water system and no leaks!  I remove the linoleum and it is all too apparent that the leak is coming from the roof, down the rear wall of the camper.  Hello this has a 12 year warranty on the roof but both the dealer and Jayco pass the buck and I am left with a camper that has a leaking roof with an unrepairable 5/8 " thick non insulated floor and no structural method of support.  We have taken excellent care of this camper as the one before it; cleaning it immediatley after we used it for a total of 12 times an average of 2 days each outing!  Jayco should have to buy this lemon back or take it to their factory to completely re-design and rebuild this Jayfeather Sport 226....
