I also tow my SS with a WD sytems. Iuse a Reese Dual Cam HP which is both sway contrl and weight distributing. The truck can well handle the relative light load on the hitch. My truck has an 11,500# GVWR and actual weight is about 8000#, so it can carry 3500# in the back. The WD hitch is set to transfer some of the weight to the front axle which does improve the ride and the steering. I am an engineer and like to make sure we have everything SAFE. With a well balanced trailer, you can never say that it will never sway. You never know when you will get hit by the sudden gust of wind from a passing vehicle, over a river or such. The sway control is cheap insurance for that one time that you might need it.

Others will set the maximum lower, but I think that in many cases this is without a weight distribution hitch and spring bars. The tricycle comparison is, I believe, not applicable as it ignores too many factors. Fifth wheel trailers, also with a triangle setup have up to 25% of their weight on the tow vehicle. The problem with too much weight is what it does to the tow vehicle. Aside from the effect on the rear axle and suspension, both steering and braking deteriorate with all the weight on the rear. The remedy is in the weight distribution hitch and spring bars, which move some of that weight both to the tow vehicle front axle, and to the trailer wheels. Again, in my case, I have neither a sway problem, nor a "wallowing" problem with approx. 800 lbs. and a 4,500 to 5,000 lb. trailer. I do have a lot of truck, but I also use a weight distribution hitch with spring bars to move some of the 800 lbs forward and backward. I have not weighed the setup after hitching up, but know that I have a lot less than 15% - perhaps 12% of the tongue weight on the hitch with the use of spring bars. -Tom ----- Original Message ----- From: <waymark1@juno.com> To: <sslist@tompatterson.com> Sent: Thursday, March 13, 2008 6:05 AM Subject: Re: [SilverStreak] size of propane tanks > 15% of 4,500# is 675#; 15% of 5,000# is 750#. 800# is above the maximum > 15% recommendation for tongue weight. > Too much weight on the tongue makes for "wallowing" by the trailer, which > is supported on a triangle like a tricycle.
