I currently have a 21 foot full size tandem with light truck tyres & AlKo torsion bar suspension. The payload is currently 400kgs. The ATM is 2160, Tare is 1760. I tow with a prado. If possible would like an extra 100kgs. I've contacted the manufacture & was told they wont increase the payload. I've read a lot of articles to say that you can, but not sure how to go about it. Any suggestions please.
Cheers..

Had mine done in January, bought a new van and the ATM was 2640kg, took it to a roadworthy inspector that also does Blue Modification Plates, he inspected it and checked the load rating on the tyres, gave me a MOD plate that took it up to 2900kg, I then had to take the paperwork to Transport Department and got new Rego certificate.

Thought I might add, took it over the Weigh Bridge all loaded up for our easter trip and it went 2760kg, would have been overweight if had not had the upgrade done.

Does Rossss have the same van with the same ALKO rubber thingos as suspension?

It will most likely be the rubber suspension units and their limitations, why you can't increase the load and ALKO have advised accordingly.

No, I don't have the same van or suspension, that's why you go to the place that does the Mod Tags and they inspect and tell you what you can and can't do.

So the manufacturer 'won't' increase the payload or can't.
If they won't, what reasons did they give? It might give you a clue as to what you do now.

And also, if they can't, is it simply because they are not able to certify or some other reason?

I would have thought they would have the answers to these sort of questions. Perhaps it's a chassis thing? Axles? Brakes? Drawbar design? Height? Width? A multitude of reasons and I know from experience the manufacturer is by far the first place to start asking the right questions.

A few things to think about to start with.

These tyres....what size, type and profile are they.....from that you can find the load they will carry using the tyre standards manual.

These tortion suspension units.....do you know which ones they are and waht their rating is.

NOW, remember if these are individual tortion suspension units, it is not a load sharing suspension. Therefore they can not carry the sum of the individual units..they need to be derated and thus the tyres also.....ALCO may give this information.

There may be other factors that the manufacturer may have considered in comming up with the published ATM. There may be very good reasons why their ATM is what it is.

Most of these vans are maxed out in the design as they come.....it all too common for people to buy whatever then realise its not adequate for their needs.

Another option is to look for weight savings.

If you are running steel wheels, changing to alloy may pick you up 40 to 60 KG depending on what you carry in the way of spares and what you are starting with.

Changing from china crockery to plastic or resin may save a few KG...if you carry a camp oven changing from cast iron to a Bedouri may save a few Kg.

Changing from steel to plastic jerries

going from 2 gas bottles to one.

A few Kg here and a few Kg there and you have your 100Kg for free.

I would contact the chassis manufacture and discuss the problem. They are in the best position to advise you. The manufactures name plate and serial number will be located somewhere near the "A" frame.

Be careful, my brother's Al-Ko torsion suspension on his fifth wheeler literally just broke in half!
