Your trailer will require brakes therefore you will need some sort of torque rods to resist braking torque. Mack camel back, six rod, single point suspensions all have torque rods for axle location and resisting driving and braking torque. The leaf springs in all these are for springing and are located in slipper pockets on the axles and thus perform lateral location duties as well.
In spite of appearances, most Macks were lightly built on a par with their competitors. Tare weight is important to freight haulers. Check out the lightweights bought by the oil companies. Single channel rails, 34,000 lb diffs and suspension, five speed gearboxes, only 9 litre engines. All the American custom builders can build a full range from lightweights to heavy haulage. Just tick the option boxes on the order form.Quote:

It reverses great due to the long draw I had put on it and the slow tracking of duals. If you ever have to move a dual by hand forget about it...they will roll back and forth but to get them to turn is a royal pain in the butt. If you are only 1 tonne for the boat and trailer, that would equate to about the same pressure on 1 axle as the tow vehicle so I think ground pressure issues would be equal??? (does drive force come into it??)
After towing my boat for 2 hrs on a very rough corrugated road on a standard boat trailer, I will be building one with air suspension ASAP.Quote:

Absolutely Ben,
And in this case it is not even just a stinking tinny that you can MIG the cracks back together when they open up. Ben, when you are setting up the suspension with aor springs I have a few tricks with regards to link ends for control arms.
Bill, I would still be interested to learn how you would propose the axle to outer leaf pack connection in a camel back setup. Solid attachment to longest leaf or to multiple leafs thus limiting interleaf sliding.

Steve, are you looking at idependant sides or solid axle? what is your tow rig? what brakes are you considering?
I think 4 of these with air bags and shocks would suffice, worked for Subaru for many years, same set up but with struts not torsion bars for the later Leone's worked well and you wont get axle hop when braking.

Sorry I cant seem to be able to just post the pic, this computer doesn't like me.

I will always run a solid axle on trailers after playing with inde swing arms for a season.
I like the load sharing, stability and constant camber you get from a solid axle.
Tow rig is a 130 with tdslugi motivation - but for the sort of places this thing will go a massey furguson would do the job. Generally our long range trips involve 200km of driving which takes all day to complete!
Brakes will not be electric (waste of time on a boat trailer) and will not be Alko et al cable operated overide (rusty waste of time). I have had good success with commodore calipers (alloy with SS pistons) and a simple over-run hydraulic hitch.
In honesty the brakes will be locked out much of the time as reversing against hydraulic over rides is a joke.

Casper,
As above - tried inde swing arm set ups. Not satisfied.
Call me picky!
If it all gets too hard I will just build it on a single axle with 4link. I just think for this rig keeping it low and settled on four paws is a good idea.

I was going to say, if you had a rover rear end, to build up another same and use it, trailing arm, coil sprung a frame.... with a bit of design it could work and then you would have a complete set of spares plus rover stud pattern and discs.... but a sals might be a bit much hahaha
brakes is what I was going to suggest...I run elec drums...good but the dodgy LR electrics can be funny in the wet...not worth it unless you need the breaking like I do.
