I'll have to disagree with this statement, If you are starting from scratch, then the B&W hands down would be the better choice. Because Stuart already has the Anderson hitch and the Air Ride, then yes your statement has some validity to it. But the B&W locking jaws that fit so well on the pin, and the urethane mounts it rests/pivots on, is as smooth a riding hitch with either the puck base or the standard below frame hitch. The different air suspension systems for the pin box are not needed with the B&W 5th wheel hitch. This is my opinion BTW, no scientific testing on my part, but pulling a heavy 5ver with the B&W system has been a pleasure to pull with and I would not go with another. I could have gotten my new truck with the factory hitch, but my B&W hitch has proven itself to me. There are more ways than one, and I respect that, but for the money, B&W bests the others.
You can disagree all you want, I have towed a lot of miles with three different fifth wheel hitches ,two different trucks, and three different fifth wheels . I have towed more years then some ,less then others, but I have towed something or other for over 45 years . I know the process .
First fifth wheel 32', second 34', the third 38' , non of them terribly heavy for their length .All towed like a dream , first two with a 16K Reese manual slider, set up properly two inches forward of the rear axle center, same truck 1999 Ford Superduty 350. Both standard pin boxes . Same set up for the 38' fifth wheel ,but different hitch 18K Reese manual slider , same truck same setup 2" in front of axle center, but MorRyde pin box, towed like a dream. Still does behind the 2014 Ram 3500, same hitch 18K Reese attached to a Reese picture frame adapter attached to the OE fifth wheel prep , still two inches forward of the axle. Now I also tow with the Andersen rail mount hitch , it is 2" rear of center of axle. Both hitches ,same truck, same fifth wheel, you cannot tell the difference which hitch I am towing with . fifth wheel ,now is probably 13,200, at times possibly a bit heavier. It tows no different no matter how its loaded, water tank is in the rear ,full or empty ,no difference. Its an older Montana fifth wheel, and has always towed great, other then when the shear springs in the MorRyde suspension needed replacing, got a little bouncy, chucking nonexistent .
I am not sure what you mean by B&W does not require air ride pin boxes, but many sure has them . I keep hearing this jaw setup on the B&W, and I fully understand how it works. My 18K Reese slider ,has the same head as the Reese Elite, wrap around 1" thick jaw, don't know if its better or worse or whatever, buts it solid around the kingpin, and is that not what it is all about ?
If I was starting from scratch with my present fifth wheel ,and truck, I can't see where I would need anything else , other then what I have now. Would I have bought into this B&W fan club. maybe, but I sure wouldn't now.
