The hose I am referring to is the one with braided stainless steel in the rubber of the hose itself. You need a hack saw or powered cutoff saw to cut it. Widely used for high pressure hydraulic lines on power equipment like back hoes, etc. Takes heat and pressure well. Not aircraft standard with teflon liner (which would be better) as that was not available locally when I needed it. The hose that fractured was of a similar, but smaller and less robust construction. It had Parker field re-placeable fittings but required a proprietary OD hose size. The hydraulic hose and fittings are a common standard size. I used 1/2" ID to get a bit better flow for the engine oil. The fittings are larger and the 90 degree uses a longer radius which gets the rubber much further from the exhaust manifold than what was on there.
The air dam was formed via cutting anti fatigue mats (the mats with puzzle like interlocking edges). That stuff is light weight, but seems to hold shape well enough. It is easy to cut and can be fastened via cable ties pushed through the material in two places and wrapped around a support member. I used rectangular steel tube to move the battery outboard to create space beside the radiator on the PS to mount the fan assisted external cooler. The fatigue mat material was cut so it formed an air path from the grill back between the battery and the radiator directing it through the cooler where it exhausts into the open area around the front wheel far enough from the tire and brake rotor to prevent any heat build up in that area. The wheel well liners have been removed as in ten years with the other coach I have yet to find a downside to doing so, but the coach runs much cooler without them. On the DS the air dam goes along side the radiator from the grill back. That stil
l leaves plenty of room for cool air to flow outside the air dam to cool off the top of the engine and provide modestly cooler air for the air cleaner.
I will report how well this all works when we do our next hot weather trip.

Jerry,
You have used the term "high quality armored hose;" I assume you mean hose with stainless steel braiding on the outside.
Please be advised that there are different types of hoses with stainless steel braiding on the outside; some of them are rubber
internally the REAL "high quality" ones are aircraft standard which is Teflon internally.
I note that you had new hoses made up at NAPA, were they rubber internally or Teflon.
I believe that the ones JR Slaten has made up for the 455 and 403 are aircraft quality.
Regards,
Rob M.
