RE: Satisfaction with Reese Drop Draw Bar
The bar performs flawlessly, in fact I have two - - one for my Overlander that requires a 2" ball and a second with 2 5/16" ball for my Argosy Minuet. The greatest draw back is that the base of the draw bar is low enough that it will drag when departing driveways with steep approach/departure angles. It wouldn't be such a problem, but I typically leave my ball mount in the receiver throughout the season as it is heavy enough to aggravate an old shoulder injury. My experience with the K2500 Suburban and this draw bar is that it takes careful shopping to get a ball mount that will allow a ball height less than 19" - - I did finally find one that I always use with my Overlander that puts the ball height at exactly 18". I haven't had the time to source one for my Minuet that will get its height back at the 18" level.
I think that you are likely on the right track with your weight distribution bars. The Reese technician who assisted me in fine tuning the hitch adjustments for my Overlander condemned my 500 pound bars as too light (they had developed a noticeable bend or belly), and sold me a set of 750 pound bars that I have been using since that time. The trailer weighs very nearly 6,000 pounds loaded for a trip to the WBCCI International Rally with a tongue weight of about 725 pounds.
My recommendation would be to consider the Reese Dual Cam Sway control. I have used this system with my Overlander since 1995 and it is far less trouble than the friction sway control that I had on my Nomad - - the Dual Cam system doesn't need to be adjusted for changing road or weather conditions as do the friction devices (at least the ones that I have owned). In fact, since I was able to get confirmation from Reese that the Dual Cam system is indeed suitable for a small trailer so long as it has at least 400 pounds on the tongue, I ordered a setup for my Minuet as well. I ordered the Dual Cam system from Ace Fogdall RVs new web-based store and received the package in 48 hours.
Good luck with your setup. It sounds like you are on track for a great towing combination!
