RE: "I really hate rats..."
'Tis the season. :P Fresh Cab is great stuff--I put a couple under the hood, 3-4 inside the coach, & one in each storage bay + the gen bay. It may be overkill (metaphorically speaking, since it'a a repellant, not rodenticide), but cheap compared to some of the repairs I've read about, & nary a sign of a critter since I started using it.
