Sorry. Bouncing may not have been an accurate description. The trailer pivots at the tires and since we are using the 30" extension, which has some play in it, the hitch tongue moves up and down somewhat erratically. I was considering the dual axle as it seemed it would reduce the amount of pivot in the trailer and thereby reducing the front trailer movement.

On the open road, it is fine. This issue is primarily on rural or mountain back roads that are not graded or uneven.

We have recently purchase a 2016 Arctic Fox 990 to be used primarily camping with our 4 seater RZR 1000. (Approx. 1500#). We borrowed a friends 12' single axle utility trailer last week and headed to the mountains. On the dirt roads the trailer bounced up and down dramatically due to the 30" extension we used, that came with the camper.

I don't believe we are at a weight concern on the vehicle (2015 ford F350 Dually w/ no specific towing upgrades at this time) with the single axle yet, but we have an opportunity to purchase a 12" dual axle utility trailer. I would have to believe that the dual axles would significantly reduce the trailer bounce. Does anyone have experience that they could share?

We also have a 20' Enclosed trailer that I would like to use at some point, but I think we are getting into many towing upgrades to the truck that we are not ready to make at this time. But may ask for advice at some point.
