I would wait until you know what the actual tongue weight on the trailer is before you buy the WDH. The spring bars in WDH hitches have different weight ratings and it is important that you have the correct bar rating matched to your actual tongue weight. The actual tongue weight is determined by going to a scale. If you want to get your WDH before you get your trailer, I would try and find out from this or other RV forums what your actual tongue weight is. Keep in mind that it can vary somewhat for your particular case due to how you load your trailer and a few other reasons. The factory published dry tongue weight is useless info. Our actual tongue weight is almost double the factory dry tongue weight. This caused me major problems in setting up our WDH as the first set of bars we purchased were significantly too small.
If the OP says money is no object on the hitch, then in the same vain, I would go the extra mile and take your TV and trailer to a scale to get weights, the actual payload capacity of the TV and the trailer and what the weight distribution between axles is. This is one of the best things you can do in any event, as you are otherwise flying blind and are *thinking* all is okay, when it may not be. We got some real surprises after going to to a scale like we are almost at the GVWR of our trailer without much really in it. Also, the payload capacity of our truck is about 1,000 lbs less than what the door jamb sticker says.
After doing some research, I ended up deciding on a Reese dual cam hitch ($450 on ebay). I had no end of trouble trying to get the weight distribution right with 800 lb bars. The rear of the trailer was also bouncing a LOT. Then I installed 1200 lb bars and then it was easy to get set up. The bounce in the rear of the trailer also calmed down a lot.
I don't believe in the Anderson hitch. It relies on compression of the urethane bushings and has no adjustment in different spring bar ratings like most other hitches. It seems to be a low tech. design and from what I have read, only works okay on lighter trailers. If OP has lots of cash, why go this route...
We have the Reese DC setup and I love it (after finally getting setup right). I love the self-centering action it has which the other friction types don't have. Many swear by the friction type WDH hitches like Equalizer and also the add-on friction bars. Many swear by the Reese DC. As an engineer, I like the design of the Reese DC. I love the performance when towing. I can see how some might have to re-adjust the cam arms if the TV is loaded and the bumper drops and/or if the tongue weight of the trailer varies, esp. as in the case of a toyhauler. We have a 3/4 ton truck and the tongue weight is pretty constant at just under 1,000 lbs so the cam arm setting doesn't need to be re-adjusted. Adjusting the cam arm nuts can be a PITA and you don't want to have to touch them unless necessary.
If I wanted to spend lots of extra $$, the Husky centerline is one I might look at.
CenterlineAnother thing to consider is whether or not you use round spring bars or the square trunnion bars. Our current ones are trunnion and the last ones were round bar. I like the trunnion ones better. I had trouble with the little spring clip and pin on the hitch head that holds the bar in place. We actually lost the pin once, but fortunately it was at home somewhere. Good to buy a spare set of spring clip and pin. There are pros and cons of trunnion vs round bars and it's maybe best to research the forums.
