Buy a 'spare'.....

look to summit at or around the 80 to 90k level. Then when you finally proper break the daily runner you can just swap over to the spare one while sourcing the parts to fix the other one.
Look to what actually wears out, and how often you manage to wear them out time vs mileage etc and build up a wee spares stock. That and good maintenance should see your truck go on for a good few years yet.
Don't forget, things like Brake Pads can (at a cost) be re-lined, just don't let them get to the metal! Wheel bearings (okay, bearings in general) can often be sourced using the reference numbers on the races via a specialist bearing supplier
This posting may have been helpfull, on the other hand probably not... Either way, I may have had drink when posting it in which case it's probably not as helpfull as it could have been
Work safe, and remember all technical problems can be resolved with a hammer, the trick is knowing where to hit it and how big a hammer to use (I often find it may also help to have a spare bit in the shed to replace the bit you have just mullered
