Don't idle your loud diesel at 5am for so long!!

I have a gasser, but it's an old 454 with oversized exhaust and cheap (loud) mufflers. It sounds like a musclecar at idle but isn't nearly as loud as a diesel idling. I also have air bags but it only takes about 3 minutes for the tank and bags to refill and for it to level itself. I never leave anywhere before 8am. If I knew I had to leave at 5am, I'd honestly ask if I could park in overflow or some other area for the night. I cringe when I have to start the thing up before 9 or 10 am.
