Man, had a rough trip this weekend towing my boat. My stomach feels like it has been put into a paint can shaker. I was (and still am) popping Rolaids like candy.

The situation is that there are a few stretches of road has a slight rise near what would be the expansion joints. (For the guys in Wisconsin, the stretch of 151 from Sun Prairie to Beaver Dam and hwy 41 from Nenah to Appleton).

Pot holes are not the issue. The best way I can describe the road is like you are rolling across waves. I think heat causes the concrete roads to buckle up a bit instead of staying flat. What I got was a nose to tail rocking at highway speeds for hours and regardless of what speed I chose, I couldn't get a smooth ride.

It seems like that when the rear wheels move upwards because of the rise in the road, when it comes down the extra weight from the trailer pushes down causing the front to rise. When the front comes down, the back rises again.

The boat and trailer is about 2400 lbs, tongue weight is not significant. Truck has 16,000 miles. I ran into the same problem with my old GMC. I have played around with tire pressures going higher and lower with no real noticable changes.

My trailer is not perfectly level as it is about 13.5" off the ground at the receiver and about 15" at the back. I have a 4" drop receiver. What I am wondering is will leveling this out help in this situation? I can go with a 2" drop making the front slightly higher than the back.

Also, is this a situation where airbags can help dampen the ride a bit?

Thanks in advance.
