Rick, If I am working in my garage, rather than run the engine just long enough to build pressure I just air it up from the compressor. I have a big one and it is always up to pressure so it is fast and easy. No I do not over pressurize it. I usually air it up so I can chase a leak or raise or lower it depending on if I am going to work on it from the pit, or if I want to drop it down to clean it. (You need aux air to work the Norgren valves to make the bus go up or down)

Short time running of the engine is not the best thing you can do for your coach. If you are going to run it, it is always best to run it long enough for the engine to come up to temperature and to get hot enough to evaporate any condensation that may collect.
