I see quite a few arguments regarding tail heavy. If I were to compare trailer loading to my RC planes, maybe it can help clear it up.
A Nose heavy plane lands fast, but lands, a tail heavy plane crashes. On a plane there is a balance point, usually landing on the spar of the wing, or in an area at the spar. For every ounce the tail is heavy, to balance you need 3 to 4 ounces in the nose.
While a Plane and a Travel trailer are completely different things, the one thing both have in common is a balance point, the plane, it is the spar, on the trailer, its the axles. Depending on where the axles are placed on a trailer, can determine the ratio of weight back to front to balance it, or make it tow happy.
Trailers that have a long area behind the axles, weight back there can be critical, for every pound added, you must add 2,3,4 or more pounds up front to compensate. As another poster pointed out, 100 pounds of clothes(really? Thats a lot of clothes) placed rearward can be the making of disaster, but move them forward and all is peachy.
So, the trailer in question appeared to have 128 pounds of stuff hanging off the back, and that can lead to disaster if not compensated for with 150 pounds or more up front.
If the trailers CG is dead center, you could add equal amounts front and back. Would I? Nope, that becomes a fine weighing game. I would always add more to the front to balance than what was put in the rear.
After reading the guys story about the wreck, it just proves what I have stated in several other posts about speeding up to correct sway. Don't! Unless you have a **** load of HP and torque and can do the 1/4 mile in 6.8 seconds, you wont be able to go fast enough to correct it. Knowing what I know about hitches now, if I found a crack in the hitch, I would not have purchased a hitch of lessor means than what is needed. Amazon can deliver to any address, and if I need a few extra days, I would take them in order to have the proper setup to take the rig home.
Great post! Especially about the speeding up when you encounter "true sway."
One thing. It doesn't matter how much trailer you have in back of the axels as long as the weights are correct. It's all about weight ratios. I know this from building one of my car trailers.
It towed great at any speed when it was just a flat deck. When I enclosed it, the trailer towed horrible. The reason was the heavy ramp door. The ramp door through all of the ratios off and it was light on the tongue.
The length of the trailer remained the same and the axel to rear of the trailer remained the same. The balance weight ratio changed a bunch and that made the trailer tow like garbage. After putting a tool box and a bunch of parts up front the trailer towed like a dream again.
