Air bags

I have a 2016 Chevy 3500 dually. The trailer I have right now has about a 3500lb pin weight. While it does sink a little the truck is not low in the back.

In the next year or so I am looking at a much heavier trailer. Right now I am 18k gvw, but I am typically less then 10k with most of the weight toward the front.

In preparing for a new unit I am considering airbags. This leaves me with 3 choices. Manual inflation, on board compressor, on board compressor with tank. Having 12 tires and the importance of proper tire inflation, I am considering going with the on board compressor with tank. I have heard if you want to use the compressor for anything other then airbags, you need a tank.

While I am sure it is cheaper to go with one of the portable ones recommended on this board, I was thinking the on board would be less trouble. One less thing to store and drag out.

Does anyone have any experience with an on board system?

My mdt has 3 tanks.. and when I want to use an external line, I just hook a line up to the gladhand connector.

With my first ram, I had manual fill up that was a pain.. on my second, I have an on board compressor... which makes life easy.

Not sure where you live but with an air tank you are dealing with a lot of condensation..that is why I have a air dryer on my mdt as well...if you have weather below zero..this may lead to troubles... but also rust.. I think I would leave the tank off but your situation may dictate otherwise.

With the weight you are stopping and navigating with (soon to be greater than 18K) , I would go with a bigger steed...maybe a 450 or 550. same floor print as a 350 dually..
