RKSWYO, I think that recommendation would depend a lot on what your tow vehicle is. I have a 1st Generation 2003 Toyota Sequoia and with the SUV's they put coil springs on them versus the Tundra (pickup) has leaf springs. Therefore my Sequoia gets quite the "saggy bottom" with even the 400 lbs of tongue weight of the 19RR. I bought a Reese "Straight Line" series hitch with 800# bars. The Straightline series is a cam based sway control built right into the leveling bars, so there is no separate shock that does the anti-sway and then bars for the leveling.
I am very happy with my Reese Straight line hitch after pulling a 3500# tandem axle boat trailer for years with my Sequoia that didn't have any leveling, sway or trailer brakes. Pulling the 19RR is a dream compared to the boat, though the 19RR is heavier and has much more wind-drag than the boat, so you still know the small block 4.7l V8 is working hard. I have heard from others with the 2nd Generation Tundra's with the 5.7l V8 and much more trailer towing ability pull their 19RR's without any load leveling or sway control. I guess it just depends if the $800 for a hitch like this (installed) is worth to you. It has to help when you get in side winds or when a semi blows by you, even if you have a HD truck that doesn't need the load leveling help.
