If going with the Anderson you may want to put a few bucks aside for a MORyde rubber pin box. It is odd that in their videos that they tout their smooth ride yet they demo it with a rubber isolation pin box. Also, don't think that a 10,000# trailer won't impart much chucking on your truck. My trailer weighs 10,000# and the chucking with a 1 ton dually was horrendous.
If I were doing it from scratch again I would probably go with the Anderson due to it's lightweight and easy hook-up feature and hope for a comfortable tow. However I would go with standard bed rails so that you could easily upgrade to an air hitch if the tow comfort is not to your satisfaction.
