I have the Andersen Rapid Hitch and I absolutely love it. It works with every truck I will own and with every trailer I want to hook to.Dad got suckered into one of these on his last truck, if you live somewhere with snow and road salt it's buggered after one winter.
We both have b&w hitches and keep the pins anti siezed.
It weighs 15 pounds, is rated for a 10,000 pound trailer and I have the greaseless balls (seriously) and can switch from 2" to 2 5/16" balls in seconds by simply turning them over. And there is a ton of up/down adjustment for the different trailer heights. Every trailer I pull is level. Just wish they would sell a pintel hitch option (talked to them but they won't make one :doh.
I also keep the pins (very important) and locks lubed or you will be buying a new pin if you keep it in the truck as opposed to removing after use.

And I will be buying a cap too.
