Hi my Newell guru friends
I need some advice please
I parked my coach after picking it up 3 weeks ago
I had started it since parking 3 times and idled for while to build up air every time since I opened slides and closed them ( to see do I still have a problem with the slide that did not want to open on the first night on our way from TX) - Praise the Lord after walking thru it with a Newell Slide Tech it worked great - no problem opening and closing again.

 When I started the coach the dash indicator showed  the pressure was somewhere around between 80 - 90 ( assume PSI) 

After idling 5 min or so it always goes up to 120 

This past weekend I reversed it out of the garage to wash and had the engine off and the generator running for 8 hours while washing ( was long big wash?).


But to get to why I am writing - after the wash  I started the coach up again aired up and parked back in garage

So this past week I have been polishing the wheels one a day since Monday - another serious long job ??

I worked my way around to coach the last 4 days and today back at the the passenger back drive wheel 
Sitting down I suddenly realize the coach has squatted down in the back ( was so shocked that I did not fully take note if  the coached only sagged in the back but I seem to recall the coach looked level) 
The back of the underside looked like it was few inches off from touching and was down to the point that the inside arch ( foam like material ) was touching the top of the tire.

I immediately started the coach and raised it up to ride height.

I had the coach idle for 20 min and switched it off
I then took my Amprobe ULD 400  Ultrasonic  leak detector ( thanks to Steve Vance you tube video) and used the parabola piece and held it all over under the coach, but could not detect any hissing sound or leak sound ( trust I used the tool correctly) 

I also took it to the driver side basement section in front of the front wheel and listened to all tubes and pipes and things that look like it might channel air through - no leaks or sounds from the instrument 

I also opened the material around the coach air door mechanism to listen if there is a leak ( when I picked up the coach the seller / dealer said he order some part since he is under the impression there is a leak but it had not arrived and we needed to get going. 

I detected no leak sound with the very directional pipe fitting to the Amprobe 

So if you guys can maybe suggest some solutions or things I should check I would appreciate it very much. 

At least I was warned their migjt be a learning curve ???
