Well I just went through the same issue. I was Loaded with 2 Farm Tractors on my gooseneck and heading 288 MIles home from NY to NH . I started to climb a hill and WHOOOSHH !!! It damn near gave me a heart attack. We put the hose back on 5 times in 250 miles. Its at the Dealer now and I am waiting for there diagnosis . Has any one had the dealer tell them its NOT covered under the 100,000 M ile Warranty ?
