This is the primary reason I got the Sonoma Minitruck. To be able to install a HydroDrop Version II.
I had attempted to install HDV2 two weeks before the final install. I was having issues when trying to remotely operate the valves. When I pressed the remote the response was not what I expected.
When I did the 2nd installation I removed the passenger seat so I could trace and visually see where all the wires went and how it interfaced with the GC350 quick valves. This is when I discovered that the 7 button wired controller did not connect directly to the valves. There was an interface control module in between the hand held wired remote and the valves.

This aftermarket AVS module was hidden below the seat under the carpet. I didn’t see this when I attempted the first installation.

As far as I can tell this module acted as a relay adding protection to the handheld button controller. The input to this module did not receive a standard +12VDC signal to activate the output. When HDV2 sent a signal the module did not recognize it and provided an incorrect response. Simple.



I replaced the old air ride control module with the HDV2 and remote. I also added an AVS handheld 7-button controller for manual use and to demonstrate you can still use a wired controller with the wireless controller.

What a difference in functionality and appearance.

I did more cleanup using another “wrap” for the wires. The previous type looked old, this one is more modern and functional.

The circuit breaker for the air ride compressors seemed to have failed at one point, I replaced it.

I grabbed carpet material from my favorite place at Morgan Fabrics located in Stockton CA. They have a large selection of just about every type of material you need.




I carpeted the rear area where the subwoofers and HDV2 is located. The material is marine grade but the equipment is not. I better not get caught in the rain.
It is safe to say that I am the only Minitruck controlling its suspension using HydroDrop II. On the otherhand, Minitruck Bed Dancers are using HDV2. One of them is using the HydroDrop II model. The rest are using HydroDrop Version 1.
