Question

Hi, i understand the lack of stability at 90 degrees, but when would you ever turn so sharply,under normal use 10/15 would be max, could please explain the problems using Indespension units because we used air bags at the end or radius arms for years with no problem, regards Don v12 trikes.

Hi Don:

I'm just talking this through in my head, so bear with me.

The Indespension beams are trailing arm, and we would need two of those at the back for the engine end of things, and one steerable at the front.

As they are trailing arm, the front axle pivot point needs to be at the centre of the axis of the wheels, so it would need to be offset by approx 100mm forward of the wheel, which implies that a sort of cradle would be needed, not a big drama but would need thinking about. The new beams that we have sitting on the floor are made by A N Other and have 80mm square beam tubes. Perhaps we should use individual Indespension units on a custom front axle?

So 6-wheel, 3-axle, 5.5metre body length and another 1.5metre for the drawbar, 7.0metres is the max allowed length for a gross towing vehicle weight of 3.5 tonnes and under. We need 2.5 metres or so for the engine, based on what we do with the trailer at present.

In what is left over, you'll have a step at the front to allow the front axle to turn underneath, so two bunks above that, and the other side against the division for the engine compartment you could have the kitchen, sink, shower etc.

I feel a drawing coming on....

7 metres X 2.55 metres are the max plan sizes, height is not restrictive.

Hi, keep the thought's coming, regards the front axle with the axel centre being 100mm back from the centre of the turn table the axle when not under load ie overrun the trailing arm effect would tend to make the axle run in a straight line regards Don v12 trikes.

We reckon, after a few fag-packet sketches, that it could all be done, and within the overall weight limit (for us) of 3.5 tonnes fully loaded. Water and waste storage not included

The existing trailer weighs in at a touch over half a ton, but it is very heavily built, and we could save a lot of weight on a new build, so if we take off the engine weight of 1.7 tonnes on its trolley, that leaves 1.8 tonnes for the trailer and fittings.

If we keep the floor low, then an interior height of 6ft 6" or 2 metres would be possible, giving storage space over the top of the engine inside the rear compartment.

What weight capacity do you need, Don?

What can your car tow?

Here's what I wrote 12 years ago:

Unless you have some serious extrusion AND a good TIG welder, I'd stay with steel, although if weight was a real problem then I'd use alloy extrusion from the bodybuilder's stock sections for the upper body.
