New Aluminum Trailer

[turbo36]

Thanx for the reply. Is there an equalizer between the two axles for traversing rough roads? I followed a double axle "lowboy" car trailer over a slightly rough road; the trailer was empty, which resulted in "severe bouncing" at relative low speed? That trailer had no suspension, which would also cause a lot of jerking for the tow vehicle? The manufacture also stated they would customize a trailer to your specifications, would that include conventional springs? Once again, thank you in advance.

Each axle is independent, there is no "linking" between them. The rubber torsion axles have been around for a long time , 20 years or more, and have become the standard on snowmobile trailers due to the low maintenance and their ability to ride smoother then steel springs. Pulling any trailer empty on a rough road is going to cause it to bounce around because the spring rates are designed to carry a load, therefore they will be "soft" when loaded and "stiff" when not loaded. This is very similar to a heavy duty pickup truck , although the pick up has the advantage of having shocks to buffer the bounce. There really isn't any "jerking" the tow vehicle, you can feel the trailer behind you but it doesn't move you around.

I drop my tire pressure to 20 psi when empty. It rides real nice and does not bounce around. I've been doing it this way for 20 years without any problems.

It is easy to add air with a portable air-tank just before I load the trailer.

I posted some pictures of my JD Tractor in the JD discussion group and had so many comments on my trailer I decided I should post some photos in the trailer section.

It is a Featherlite model 3110 car hauler- 8' 6" wide by 17' 6" long.
The GVW is 7,000 lbs and the empty weight is 1,400 lbs.

I need a new tractor trailer with a GVW of 10,000#, and wasn't sure they made aluminum ones that large with torsion suspension? The higher weights for boat trailers resort to the equalizer with springs. I like the torsion with the low center of gravity for suspension, stability, and ease of off-loading. Some recent boat shows, display some larger boats with both. I am still pondering the long term effect, with the constant weight on the trailer for long periods of time? Thanx again for your replies.
