By your own statistics it would seem that you still have at least another 7 years of use! By that time, hopefully Pentax will have released an even better equivalent model. However, if your K-70 succumbs to your harsh usage conditions in a shorter term, perhaps you should replace it with a new K-70. Incidentally, if you have not yet done so, you might shield it from vibrations by lining the tank bag with some thick foam plastic.
P.S. A good set of good images.
calculations are correct but I had a slow year for this camera due to switching to Pentax and a learning curve, and I was carrying multiple cameras, now this is my main one, I do average around 100.000+ shots a year so if it lasts until 2020 I'd be surprised.
The camera is well insulated BTW.
