i will take a stab at a few of these.....
1) the "leveling valves" the shop was referring to, is that the same thing as "ride height valves"?
in the way they are referring to leveling valves (saying there are 3 of them), means they are talking about the ride height valves. on yours, there are 2 in the back and 1 in the front. the back ones are easy access. they are right at the outside of the rear wheel well towards the front of the coach. you can reach them easily. yes they do leak, but not real often.
(2) how many in total such "leveling valves" are there on a coach with ZF suspension/steerable tag? My coach is 2004-701
as above, there are 3.
(3) how many "ride height control rods" exist on a coach with a ZF suspension & steerable tag?
each ride height valve is attached to a single rod. like i said above, they are easy to see and reach. they just pop on and off on the bottom to a pin. yes, they can slip at the top and it is possible the rubber grommet like thing could be rotten, but i have not seen that. but they can slip and just need to be tightened once adjusted correctly.
(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?
in a valid system you have 2 six packs. one in the front and one in the rear. they are mounted in the rear engine bay passenger side on the firewall. each six pack has 6 solenoids. 2 travel, 2 raise and 2 lower. front travels are tied together since there is a single ride height valve in the front middle of coach.
(5) If you have pictures of the above, and part numbers (with ZF suspension & steerable tag) would you please post them.
valid is very good with technical support. i have talked to them a number of times and they are great.
(6) a loose or unsecured rod as shown in the photo, will it cause the coach to height drop in normal driving mode?
a loose or unsecured rod will cause problems depending on where the ride height level arm is at. could drop it or raise it. and that would only be when you are in travel mode.
(7) how many the total number of such height control rods on 2004 or later models with ZF suspension w/steerable tag?
same answer as previous. one for each ride height valve. a total of 3
(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?
that is correct. the travel solenoids isolate and take the ride height valves out of the system when you are not in travel mode.
i do not have a valid system in mine but i have helped 3 different folks with them and have changed ride height valves and played with the valid solenoids. so i have at least a tiny bit of experience.
i am sure there are gurus on here with more experience with them than me but i thought i would share what i thought. anyone feel free to correct anything i have said.
