I like Richard's idea of replacing the Viton switch/regulator and will likely do this when I get the coach back home. However, in the meantime we would like to continue our road trip. I see some people have suggested replacing the Thomas with a small all-in-one unit from Harbor Freight - is this something that could be a full time replacement? it looks a little light duty for the coach, but it's self contained, only needs a 120V feed, and it's inexpensive.

Is there any issue running the coach without the 120V compressor? As I understand it's major function is to keep the coach level when the engine is not running - the 12V compressor can handle the doors and potties when parked overnight (have to work on finding level spots!)

My two 120 V compressors have a toggle switch to change from one to the other and it performed as expected a month ago when I picked up the rig.
Now if the switch is to the left the right unit runs and if it is to the right both units run. I have not opened the box yet, but thought any advice before I move in with screw driver in hand would be helpful.
I have owned many motor homes, but never one like this.

It appears that Seat Specialists can get the Right Hand kit likely custom since the truckers seats are left hand. I'm picking up an inline ball valve to turn off the air line when we are not on the road...

Before I purchased Coach #416, the Thomas 120VAC Air Compressor was replaced by a previous owner with a Lowe’s Kobalt brand air-compressor.  It made all kinds of racket like you would expect it to when it ran.  I removed it and have regretted it since as I did not have a replacement on hand.  I do not know what model Thomas was in there originally and how it was plumbed or wired next to the 20kW Kohler Generator.

The 120V Air Compressor is used to level the coach using the air bags controlled with the HWH Computerized Leveling Controller.  The main engine-driven air compressor does the duties of filling the air bags when rolling down the road.

I would appreciate information provided from anyone who replaced their 120VAC air compressor with the Thomas or an equal or better compressor.  Photos of their current or new air compressor arrangement showing plumbing & wiring would be fabulous.

Question: If boondocking, would not a 12VDC air compressor be preferred to a 120VAC air compressor to keep the coach level when parked?]]>
