I talked to Fastway and they just asked that I send them a picture of my current setup. I sent them the attached picture. They noticed that the bar was not parallel with the trailer frame. They suggested I lower the L bracket so that the bar is parallel which ensures it lays flat on the short part of the L. I made that change today and drove 260 miles and had no issues. I'll give it a couple more trips before I declare it fixed, but I think that was the problem.

On the issue of weight:
It is interesting that so many people immediately decided it was a weight issue and Fastway was not concerned about the weight at all. Turns out weight was not a factor.

I do not understand all of the comments saying my weights are unsafe. I am pulling a 9,000-pound trailer (fully loaded) with a truck rated for up to 17,000 pounds. The truck is rated for a 1,700 tongue weight and my trailer is 200 pounds below that.

Several people have pointed out that the dry tongue weight on my trailer is around 865 pounds. Given that all of the storage for this trailer (including the fresh water tank, food, dishes, clothes, etc) is in front of the axels, it seems reasonable to me that when fully loaded it is 400 pounds higher at the tongue.

Oh well. Thanks for the helpful suggestions.
