UPDATE July 2014: Just finished a 4,700 mile, 40 day trip from Texas to Okla, Missouri, Kansas, Iowa, Minnesota, Wisconsin, Illinois, Indiana and back. Towed in rain, up and down Missouri hills, through narrow construction zones and on rough back roads. The Anderson continues to perform beautifully. Chucking is almost non-existent. Sway, although not totally eliminated, is only slight and only when large trucks pass at speeds greater than 20 over mine. The sway is not the same as without a WDH, rather both the Car and Trailer feel and react in unison and it really is very mild (my wife pulls now from time to time and before the Anderson, she said she didn't feel safe).
Just before the long trek, I had a weld shop add a frame welded receiver to the back of my trailer and I now carry a GearDeck17 box that holds a generator and grill (adds about 300# to the rear).
I continue to start my long trips with a visit the CAT scales and make sure that I manage my weights at spec (600# tongue and trailer 6,000# or less). If adjustments needed, the car has surplus payload, so on occasion I move something out of the trailer or storage into the SUV.
