Thread: Road user charges

I have an old bighorn that is used almost exclusively for going bush, river beds etc. I have a work ute, so the bighorn is just the mission mobile.
I am getting tired of putting road users on it when I am not using the roads most the time.
Is there any LEGAL way around this without being a business or farm etc?
I do not want to go the odo switch route as legal concern and also wanting to keep the odo accurate to keep track of service schedules and the like.
Cheers
