I had hoses blow their ends off on my Itasca Suncruiser. HWH really took care of me and replaced the lines with what looked to me like steel gas lines. The problem was the design on the hoses that went across the automatic transmission from the side with the pump to the large slide and jacks on the opposite side. The poor air flow and heat generated by the Allison transmission exceeded the strength of the fittings and the hoses. Replacing them with steel seems to have solved the problem.
