Question:
I have a 2012 Winnebago Journey w/air brakes and I would like to setup my 2012 Chevy Avalanche to flat tow. Could you put together a parts list for me. Please! Thank You!

Hey Todd! I looked through the parts you ordered and you're pretty much set. The etrailer Classic Base Plate Kit # e98959 will fit as long as you have the 4WD model. Since you're getting the etrailer XHD Non-Binding Tow Bar # e94ZR you probably won't need a high-low adapter because it has a built-in rise/drop, and safety cables are included.
The Roadmaster # RM-15267 is the best option for wiring and then the Demco Air Force One # DM26VR is what I would have recommended since you have air brakes. This doesn't drain the battery so a charge line won't be necessary. All of this together with the TPMS system # TM56FR will give you a really nice setup.
Where are you headed once you get everything installed on your Avalanche?

I installed this on my 2016 Tiffin Allegro Bus 37AP with powerglide chassis. It was tough determining the correct airline to splice into but I got a little help and it worked great. It was also difficult with my RV to find a good place for the tank. Yours might be easier. The problem for me was that there was not space to get the drill into the tight space to drill the mounting bolt holes. But I managed to find a good spot and it's working fine. I installed the wireless remote lights in the cab and have had great success with it once I properly adjusted the sensor on the pedal air cylinder. Love it.

Mostly same setup for me. Freightliner Super C and 2013 Avalanche. I’m sure everyone’s experience is different but I wouldn’t suggest the Air Force One system without the remote monitoring. Adjust it properly initially and it really is a set and forget system. I found the audible beep tiring but it switches off with a switch on the back. It is directly in my view so no chance of “not” knowing it is working. If you pass on the remote monitor, the led strip you would mount on the back of the mirror of the Avalanche is almost impossible to see in a back up camera. I prefer to look forward during breaking as that’s where the action is. It’s comforting to see in my peripheral vision the brakes being applied in the toad. I made the decision for Blue Ox base plates as it is more “stealth” with the tabs removed. I ran my own wiring and used the diode kits for the tail lights. It was cheaper than the other plug-in harness and the majority of the work is running the wires. I chose to add a charge line on the truck. It was already in the plug on the coach and can’t hurt if the brake lights are being illuminated a bunch. Only other “tip” for the Avalanche was I through bolted the cable anchor for the brake actuator. The metal was to thin to ask a self tapper to take the strain of the cylinder pull reliably. Pulled back the liner in the fender well and it was accessible. Take your time and it’s not bad. I did the coach one day and the truck another. You will love it once it’s done and start using it.

I got the same system for my Newmar Ventana. I would not recommend the wireless LED monitor, although a nice idea it has never worked, don’t spend the extra money. Installation is a little challenging but the instruction are pretty good. Other than the monitor system, the brake system works well.
