Routinely scraping all the glass (not just the windshield) with a safety razor will go a long way in preserving not only the wiper blades, but also the rubber channels for the side/rear windows too.
CAUTION! None of this applies to mirrors. Don't scrape or wax your mirrors!
We are all familiar with how paint over-spray will quickly ruin the edge of the wiper blades, but not every one thinks about "chemical fallout", which can also, although not as quickly, do the same damage.
After washing the truck, wipe your bare hand across the glass. It should feel as smooth as....well, as smooth as glass. If it doesn't, take 10-20 mins and scrape. You'll hear, what's been described as, clicking sounds as the razor removes the bumps. To make the job easier, I first apply a synthetic wax to the glass to act as a lubricant and it makes the job go a lot quicker. Finish with a damp microfiber to remove residue and buff out the wax. Now, wipe your hand accross the glass again and feel the difference.
Also notice how your wipers operate silently, indicating there's less friction. Same for raising and lowering the side and rear windows. The wipers will aslo do a better job of removing rain and debris.
Final notes:
You don't have to use wax if you're opposed to the idea, as many people are. You can use water or glass cleaner instead or nothing as you see fit.
When cleaning the inside glass, tinted or not, I recommend (and so does Toyota) using only a cloth dampened with water. Of course, if there's any grease or such, you'll have to use something other than water. But for that "cloudy film" you see, water will do the trick and leave no streaks.
