Thanks for your reply Old-Biscuit! I am from the old school, if it ain't broke, don't fix it! I was hoping to hear from a knowledgeable person, to tell me go ahead, adjust it. I was happy to see you were the poster! I know my problem was not serious, but I like to have things work as they are designed.
I will be camped at 5,600' for a couple weeks, so probably won't run the AC much. I'm sure there will be rain/thunderstorms, on and off, thus my concern about creating any leaks by adjusting.
