Last September, I replaced all of my drive axle air bags, and in May before the rally, I plan to replace the tag axle air bags which I now have.  I think I have a serious air leak at the drivers side rear, and would like to replace all of my HCVs while in the shop.  I researched the forum and found that Richard and Tuga gave the valve numbers from Dayton Air Control Products back on Aug. 12, 2012.  There are only two valve numbers, one (K870005) for both the passenger side rear and the front, and a number (K870006) for the driver's side rear.  I assume these are the "grey" colored valves the Richard mentioned in his post.  I had assumed that there were three HCVs in the front, one in the center and one on each side for leveling the coach.  If so, should not all three of the fronts be replaced, or just the center one?  Any other advise would be appreciated.  I read one post that Ron Skeen replaced his with King Of The Road valves, but special brackets are required.  I need to get my valve order in soon so they will be delivered in time.
