Hello, I have a 2016 Dutchman Voltage 3605. I am looking at the trail air system for this rig. Could you please provide me with some input on what would be the best system for this rig?

I did some research and it looks like the 2016 Dutchmen Voltage 3605 comes with a Tri-Glide 21K pin box but it is unclear which specific model it is. There should be a sticker on the pin box that indicates which model it is such as an L05 or some other 3 character code.

It is likely based on a Lippert 1621 or 1621HD pin box which would mean that # LC158778 would be the correct replacement. To be sure I would need to know that 3 character code on the pin box. If that is not available there are a few measurements you can take to determine which pin boxes fit. I have included a link that shows where to measure.

The TrailAir pin boxes reduce vertical and horizontal movement for a better ride when towing the trailer so it is an excellent choice!
