I have been using dot 5 in my street rods for 30 years. It keeps everything real nice inside. I don't worry about rusted wheel cylinders anymore like I did with dot 3. I converted the GMC to dot 5 just by flushing the old fluid out with new dot 5. It was OK for a few years but then I had problems on steep mountain grades (brake pedal went to the floor when the brakes got hot). If you are running dot 5 in the GMC I would change it just like dot3 as it will wind up with water pockets in the system and if that happens you will loose your brakes at the worst possible time. It is a lot less expensive to change dot 3 or 4 every couple of years. If you never get the dot 5 hot it will be OK like in my street rods.
