I tow a 31 foot 84 Excella with a 1 ton GMC 12 passenger van.
I was also experiencing problems with stability.
I adjusted the distribution bars until the two vehicle squated evenly and the trailer was level.
Then I went to a CAT scale.
Every thing was way off.
NOTE: If you are going to add weight to the tongue, do it first.
I adjusted the ball height and distribution bars over the course of an afternoon until I had equal weight on all four axles (two axles on the van, two axles on the trailer).
I now have between 3100 and 3200 lbs on each axle. The trailer isn't quite level but what a difference in handeling, stability and stopping.
After you get the weights balanced between the axles then you have to adjust the dual cam set up in accordance with the instruction manual. I have the older dual cam and all I did was loosen the u-bolts and the arms jumped home all by themselves. The dual cam high performance you have to adjust.

In the large picture in the background is my red and white GMC van and my trailer. It does not look level, however the weights on the axles are as equal as I could get them and the unit handles great.
Its the weight distribution on the axles not the appearance that stabilizes the rig.
Hi tarheel (Rick) Don't forget to bring the wheel locks to Williamsburg please.
