Well after using the schematic and writing down each assembly # I got a handle on how everything relates to each other. I called HWH and they have responded magnificently. I am on the way to correcting the leaking hoses. The technicalities of routing are a huge issue on this unit for the top and bottom rear cylinders. The Winnebago 430V layout is the prefect storm for the 4 hoses. The space of an eight inch square with about two inches depth has the Main wiring harness, fixed black pipe and gas oven lines, frame cross member and shock mount, another cross mount, upturn in frame, large body dampener, four 1/4 inch hydraulic hoses, two other harnesses, the four 1/8 inch hoses going to slide all crunched together with not one iota of wiggle room for anything. Behind all that is the access channel with two hard turns to negotiate. To get to the channel cover might require removing the rear wheels. Oh joy!
