I don't think there has been huge increases in the price of a new truck for several years, but I do think there has been genuine improvements in them, both with reliability and sheer performance. Manufacturers seem to have settled on a good platform and improved it instead of moving on into the next level because the old platform wasn't working well.
When one looks at car issues it always spikes high with a new model, then after a few years things start looking much better if they keep improving what is offered.
Buy a new truck, but not a new model platform.
