Posts: 6,049 Sebring, Florida. | I usually haul a 3 horse goose neck type trailer, never had any sway problems because of the goose neck hitch, it's located in the truck bed just in front of the rear axel. I can take both hands off the wheel at 65mph and it tracks straight.
BUT, I once had to haul a 24' box trailer with a bumper hitch. WOW, what a difference. Way Sway! It was not all that heavily loaded, just one aiplane inside, I would guess about 1,000 lbs. of cargo plus the wt. of the trailer, but when I got up to near 65, it would start to sway, slowly at first, then a much larger divergance, so I gently slowed it way down to about 50. Much above that and the sway would start again, there was a cross wind blowing though.
This was behind my wife's Suburban with no sway bars. I was real glad I bought the goose neck for hauling the horses, but I've never seen one used for our boats. I nearly piled up the truck and trailer when on the way home from dropping off some horses two weeks ago at Auburn, I was coming down I75 South, around Gainsville about 11pm following a semi truck about 100 yards ahead, in the rain, at 70 mph he locks up the breaks and starts to slide! I jumped on my breaks and could feel the antiskid cycling, luckily the trailer was empty or I would have plowed into the back of him. But it stayed straight behind me.
There had been a 3 car pile up ahead, blocking the left two lanes. We tip-toed around to the right and got by the huge mess just before the police showed up and blocked the highway completely.
Chris, I'm sorry to hear about all the damage but glad everyone came out unhurt, have a great regatta. All the bad stuff is behind you now so the Wind Gods should be good to you!

Within reason I guess, you don't want to put more on the tow vehicle than it can handle. | | | Re: Trailer Crash

Posts: 5,590 Naples, FL | My memory is failing, I think my trailer dealer said anything above a certain load capacity and/or size has to have brakes on all wheels in FL.
Also, the capacity stated on a trailer and or hitch is based on properly loaded and equipped trailer (sway/load distribution bars).
Wonder if trailer brakes could have helped in this instance. Maybe not...

There were working and recently inspected brakes on both of the trailer axles. | | | Re: Trailer Crash

Posts: 5,590 Naples, FL | wow, I had no idea a blowout would result in something so dramatic. Forgot to ask how many axles (sounded like more than one)?
freakish...
How much do the masts cost?

Tounge weights one thing but how it's distributed is the most important. I can't remember the exact ratio but it's something like 70 percent of the weight needs to be in the front of the trailer wheels. Also If your towing a high profile trailer more than 14' you should have a friction type sway control added to the hitch. You can find them at Reese.

I know you didn't ask my opinion, but short of getting something that you need a CDL to drive its tough to beat a long box, crew cab dually for towing trailers. The longer wheelbase, the wider wheelbase, and having more rubber on the road are all things that help maintain and regain control. 24' is about the max I would go for a bumper mount trailer, any bigger than that and it just gets to be too much weight being carried poorly. | | | Re: Trailer Crash

I have hauled all kinds of stuff(Bobcats,tractors, WF's HT trailer with four 18HT's and a supercat 22 on it) with my F350,F250 single rear tire with bumper hitch and never had a problem if you load the trailer right.
Sorry about your accident and hope you get it all sorted out. That was a tough break Chris. I agree with Dave that you should be able to safely haul 5 boats in your trailer. As you know, I work in an industry that uses enclosed trailers extensively. It is not rare for someone to blow a tire but it is usually just an annoyance rather than an accident. You are severely under gross with your load. Many of our racers have ramps inside to double deck two cars. That is much heavier and with a higher C/G than what you have. The key is to have enough tongue weight and always use equalizer bars. There is also a special friction sway reducer you can get that attaches between the hitch and the trailer. Yes, a dually will offer a more stable platform, but with your load it shouldn't be needed. That tire pressure device someone posted looks like a great idea. Your reaction when a tire goes is critical. Once the oscillations begin, you are usually screwed. NEVER hit the brakes and try to stay in front of the trailer. It may even be best to accelerate a little until you get everything in line and then slowly lift off the gas. If you think about it, grab the trailer brake control and use that to slow the rig down. Even with blown tires, the trailer brakes should be somewhat effective. Most of this is counter-intuitive so it might be wise to experiment with your trailer braking techniques before an emergency application is needed. Until this actually happens to you it is hard to anticipate the dynamics. Fortunately I have never lost a rig but have had some hairey close calls. Good luck guys and don't give up on your concept. BTW, as a replacement I would recommend Pace American. They have a special anti-sway axle system that works very well.

These tires have thicker side walls and allow higher tire pressures which help to reduce sway in the tow vehicle. Example, I have Michelin LTX tires. You can buy these tires in four different load ranges. The Tire Rack is a good place to research tires and purchase. Tire Rack
