Don't let anxieties ruin your trip. Good to be prepared, but you are worrying about things that are no big deal. We have camped in rest stops, truck stops, and Walmart parking lots when we couldn't find a good RV park at the end of the day. Semi truck drivers navigate big cities all the time with a 54' trailer so you don't have to worry about a 29' camper. Perform some due diligence during your preparations, but the best part of RVing is freedom, and no stress of hotel reservations, airports, rental cars, etc. Don't ruin the experience by worrying about a load of non-issues. Keep your plans flexible and enjoy your trip. It sounds like a fun one.
PS. I've never checked my fan clutch before a camping trip and I live in the hottest city in the US :)
