We left our coach in Denver last month and flew to Los Angeles for a little Grand daughter time. Freezing was not going to be an issue as we  (I) had checked the weather predictions. You know where this post is going. Day three of our vacation away from full time rv life, I saw that it had been getting in the teens at night in Denver. Whatever damage was done was already done. 

 When we returned to Denver, with a little block heater time, the 8V92 came quickly to life along with the engine co

It's early, I have too much coffee, and it's too dark to play outside. 

This time of year, the forum gets a fair amount of commentary on air system weirdness and leakage. 

We all know that water in the air system creates rust in the tanks, the rust creates debris that can migrate and clog small orifices, and air valves such as the Height Control Valve, the potties, and all the air operated doors can experience problems. Not to mention the possible contamination of the braking system compon

Have 2007 Coach 797 with Valid Air Trueline Leveling System. Two Thomas compressors. 166k miles.

Coach Thomas compressors, at Newell, came on every 40 minutes for 30-45 seconds. N

I'm now getting just over 1.3 minutes of compressor off time and about 1.25 minutes on time. I had the system performing in excess of the 45 minute rate just last month. I am on my way to Vancouver B.C. and need a shop with a pit that can search out the leaks. I cannot get under the coach well enough to find the problem.  

Spokane would be a good stop for me or the Seattle ar

I can't find any air leaks.  Loosing about a pound a minute when parked. 110volt compressor cuts in at 70 and cuts out at 90. Runs about 5 to 10 mins every 20 mins.  I have ruled out the air bags and the leveling, stays level with the leveling system off.  Only 3 air powered items, the toilet, drivers seat and an interior sliding pocket door.  Soapy watered everything I could find and I do not see or hear any leaks.  

Could a 110v compressor be set up only on the auxiliary side of the air sys
