We are through hiking today. Call me if you think a 3rd party observer could help deal with your stressful situation. 8172232056

Leave a message, my phone doesn’t ring unless you are already in my contacts. Sorry about that, but I already have enough car warranties and Medicare insurance plans.

Richard, 

Thank you so much for being so kind and gracious to offer your knowledge and valuable insights.

The towing company came back with 2 drivers the next day, and finally, we got the 701 coach back to the same repair shop yesterday.

The tow truck driver spent about 4.5 hours on 1st day, then another 4 hours the next day mostly underneath the chassis, making some disconnection/connection and pumping air in order to raise the coach high enough to be towed. During the process, the tow truck driver says he found the problem why the coach lost air and caused the coach to drop (thus tag wheel touching/scrubbing the chassis) - he pointed to a rod - he said this was loose or they didn't put in the right place. See photo.

I relayed this info to the shop, and the shop manager quickly rejected that saying that's unlikely. He says it must be something else. Today the tech from the repair shop wrote to me:

"..it seems like the rubber grommet for the passenger side rear leveling valve came apart. This caused the rear side to fall. Also upon inspection it seems like the air bag for the driver side front wheel failed also. Our concern is the condition on the remaining air bags and leveling valves. We recommend the following repairs at this time.

 
Replacing remaining 6 air bags. Which are different from the ones we purchased from the last repair.
All 3 leveling valves.
Replacing 2 batteries. Batteries we have in stock. They are $371.04 each.  We also need these batteries to continue working on the RV."

I responded and gave green light to proceed with all recommended. 
As a matter of fact, I had provided 4 new airbags for the initial repair (I ordered these 4 airbags from Europe because there was no availability in the USA, and the shop doesn't have availability). They only used 2, they put the 2 unused ones in the RV storage tray. Now they suggest replacing all remaining airbags. I am fine with this.

During the initial repair, the shop also replaced 2 other items:
Item#1,  VTL02A001-1, Controller, Leveling V1 Compatible. 
Item#2,  VTL01A003-1, Sensor, Leveling V1 285kbps, (confirmed as higher version and direct replacement for VTL01A003)

 

I wonder on my 701, do I have a total of 3 leveling valves? Who is the maker and what is the part number?
