Happy to report that the install is complete and it actually works! I followed this video from etrailer.com for the Jeep Wrangler install.
The most challenging part was getting the bolts out to move the driver's seat in the jeep. They come pretty tight from the factory. I did need the extra wiring, as shown in the video, connecting the brake away switch to the 12 volt power supply. The video does not show the install of the break away switch and air supply connector that go on the front of the jeep, but the instruction manual that comes with the AFO is sufficient. The installation on the jeep took longer than the coach install and is pretty simple, after watching the video a few times.
Regarding the coach install, I decided not to put my life in the hands of the levelers and drive the coach up on wood blocks. I did use the leveling jacks as a safety backup, in case the wood blocks failed. The most difficult part of the coach install was removing the plug for the metered air connection on the tag axle relay valve. On the 2017 Anthem, Spartan put this relay valve in a very difficult place to access.
There was no way to get my hand up in there to loosen the pipe plug. I was about to use the relay valve on the drive axle and cut into that metered air hose, until I thankfully realized that it was a 1/2" hose and not 3/8". I finally got the plug loose on the tag axle relay valve by using a ratchet with a long extension, a long socket that I could fit a big allen wrench in and using the "L" part of the allen wrench to slip through the round end of a 7/16 wrench and putting the "U" shaped end of the wrench on the square plug. After a few attempts, it finally loosened.
Once a was able put the metered air fitting in, the rest of the project went quickly. Just follow the video link above. I did install the coach air tank assembly in the engine compartment, as others have shown in previous posts. That worked out great.
The attached pic is the tag axle relay valve and the plug on the bottom is what needs removed to hook into the metered air. Let me know if you want pics of the complete install.
