Long read, sorry!
I have questions about the tag pressure regulator.
My original 2005 regulator was right at the cutoff point when Monaco switched from a 60 PSI unit to a 160 PSI unit. I removed my broken and leaking 60 PSI unit (gauge was broken, regulator leaked) and installed the 160 PSI gauge unit. Took it to the scales, weighed it, adjusted the regulator up a couple of times till I got all the weights where I wanted them. Noted I was at 55 PSI on the newly installed regulator, fully loaded with 10 days of dry camping gear, food, water... This was 2018 and about 60K miles ago. I have had no driving or tire issues however, "every" time I check the regulator it could be at 60-70-80, 40, you just never know. Even if I lift the tag, it will still read whatever it was reading before lifting the tag.
The most reliable way to see what it is set at is to dump the suspension down a little then let it relevel itself. As soon as I drive it even .5 miles, it will read some ambiguous number. I try to check it only on level ground.
I know Monaco has a proportioning component to the suspension but I am just not clear on how this all works. I presume the regulator is sending air to the tag through another component that proportions whatever pressure was set to eventually get to the tag.
The tag tires never look overloaded, flat on the bottom or differently loaded nor does my steer axle. I would think that if the tag actually had 80-90 PSI sent to it that the tag would look more loaded, especially since I only run 85-90 PSI in them.
Further when the tag is lifted, the tag bags ARE empty but the regulator will still show whatever it was before lifting the tag so I am sure that number is not in series with the tag bags themselves.
I also presume that this is why the 60 PSI regulator/pressure gauge was replaced with a higher capacity unit.
There is more but I will stop here for now, hoping someone can clarify how the tag system is ultimately controlled.
Thanks you.
