I want to make it clear, I am not against ATW in anyway and think they make good products. I am just being open minded and looking at what options there are.......
If you modified the Canter with the ATW suspension and if you where somewhere other than SE QLD, you may run into problems if you need spares in a hurry. As the suspension is not standard........
I don't own a Canter and I'm not a customer of ATW so maybe that disqualifies me from comment! In the end every product is the sum of its components and good design includes choosing those components wisely and INTEGRATION into a harmonious package.
So, for ATW, all the hours on CAD, the time at the track and the mass of equipment has to be paid for. You can get springs anywhere but how many have been tested to the satisfaction of the Transport Department. I don't hear anyone out there offering to work in the commercial world for nothing, which is essentially what is being asked if the product costs more than what you want to pay.
The flip side, You can't make a UNIMOG out of a Canter. The Double Dutch couple in South Africa aren't having the run they expected with some mechanical difficulties. I have no basis to suggest that they are influenced by the modifications but the outcome is a highly bespoke and expensive new truck in a country where the base vehicle warranty is not honored and the custom bits for the camper body aren't available in country.
The Canter as delivered is suitable for its intended market. The drive train articulation matches the suspension travel etc. The ATW suspension package is, I'm sure, as good as you will get. As we move to the extremes in suspension packages, the integration with the standard drive train becomes tenuous and so the secret is knowing when to stop.
Personally, I'd line up at ATW for their earlier Canter suspension packages as I consider them solid and effective improvements to the base design. If I really needed that:Wow1: much more than that (and long distance expedition type reliability) I'd put that 25 odd K into a chassis that came with that level of suspension integrated into the design. Whilst ATW could probably turn out a completely bespoke vehicle in time, they will never have the customer base to amortize the millions in development costs spent by the major players.
