2T van - 1 or 2 axles

I had blown out - rear tyre - on my 2 ton boat trailer at 100 kph and it was just a lazy pull over on the Logan Motorway and change it....it was nicely taking the weight on 3 wheels. Custom leaf springs and nicely set up trailer - beams. Impossible to move sideways without the vehicle attached is the only issue.

My van is single axle independent suspension. Tows very well. Cant help wondering what manner of drama it would create if it had a sudden blowout...i run light trucks on all trailers.

I have a 1.7 tonn caged up box trailer and it tows beautifully also...heavy duty leafs and beam. Needs a load though.

Cheers

We ended-up with a tandem trailing arm independent with coils & shocks and Alko stability control which hopefully will assist with the RR's trailer assist if a rear van tyre blows.

Been thinking about this for a while. My 2t tandem tows beautifully. The single axle 1t Crump & Cornish is much easier to manoeuvre in tight spots. The Track is brilliant.
If I was towing a van in the bush around tight tracks, I'd probably lean towards a single axle.

and hopefully something that weighed a good deal less than 2T empty.

This is actually my preference.

I wanted to build it into my last trailer build but at under 500kg I couldn't justify it. I don't know what its called but single spring, single axle but seesaw with tandem wheels on each end.

I've seen it referred to it as simplicity suspension but I think that's the brand name.

Walking beam. The same as the back end of graders.

Yeh, That's it. I have towed farm trailers with it and it seamed to work very well. As the trailer goes over a bump or pot hole, if the obstacle is 100mm in height the vehicle is only affected by 50mm as each wheels passes over the obstacle. It's not quiet that simple as the single spring needs to support the whole weight so even though there is half the movement this doesn't translate in to half the bump being felt by the vehicle.
