Hi John, I haven't seen one,but I did see a Continental today that was fitted to a dual cab. They were 305s and had a much finer tread.The guy I was talking to had used them on sand and said they were good. It all depends on what the usage is going to be and what is best for the application.Mine fitted with 33x12.5x16.5 are great on the sand as they bag our well.But in remote areas they are hard to find,and don't have the weight rating when you carry a lot of gear.For the Simpson trip I didn't have the camper on as we slept in swags so weight was not an issue.But we did drive hard.
There are 3 other canters in my area that I have made contact with that are invarious stages of build ups.Also an OKA ,but will leave that alone.
Maybe we need to start a Canter Camper Touring Club.
Now that I am getting a chance to look at all the threads I can see you are a goldmine of information.
Talk to you soon.
