While my 701 has been towed back to the repair shop last week, I'd like to seek some input on some questions 1-7 below,

Background:  the saga was posted here http://newellgurus.com/showthread.php?tid=6843, before that, the coach had just done the 1st repair (since I owned it) by the shop, that repair included replacing 2x airbags on drive axles, 1x VALID control panel, and 1x VALID leveling sensor.

   

   

   

   


Now the coach has been towed back to the shop several days ago for further check and they came back with findings and suggestions, the email from the shop says

(a) "...it seems like the rubber grommet for the passenger side rear leveling valve came apart. This caused the rear side to fall".*
(b) "...replace all remaining airbags" (2 airbags already replaced during the initial repair).
© "...replace all 3 leveling valves". 
.

I'd like to see if someone could help me to understand a few things.

(1)  the "leveling valves" the shop was referring to, is that the same thing as "ride height valves"? 
(2)  how many in total such "leveling valves" are there on a coach with ZF suspension/steerable tag? My coach is 2004-701
(3)  how many "ride height control rods" exist on a coach with a ZF suspension & steerable tag?
(4)  I read some thread mentioning "travel solenoid", is this the same as the "6-pack valve"? How many "travel solenoid" or 6-packs in total in a coach?
(5)   If you have pictures of the above, and part numbers (with ZF suspension & steerable tag) would you please post them. 

* earlier, while tow drivers were working hooking up the coach and his semi, the tow driver told me (also he told the tech at the shop upon arrival): "Found the problem was the riding height rod was not fixed or loose...". so they fixed that problem on the spot. Since they couldn't restart the engine (dead batteries) they had to tow it.



     

But the repair shop manager rejected what the tow drivers were saying, he says instead: it's unlikely a loose leveling rod would cause the problem I was having - coach height drop. It's most likely something else has failed, which they came back with the above comments (a), (b), and ©

Now, here are my additional questions:

(6)   a loose or unsecured rod as shown in the photo, will it cause the coach to height drop in normal driving mode? 

(7)   how many the total number of such height control rods on 2004 or later models with ZF suspension w/steerable tag? 

(8)  those height control rods, function only in riding or travel mode,  and do not play any role when the coach is in park/stationary level mode, is this correct?
