Ah, good suggestion! We had a similar issue here after an Ocala Forest meet and several had mud packed in between the radiator and evaporator, which you'd never see unless you lifted the rubber flap that covers the gap between the two. Of course, unless you've been wheeling there shouldn't be anything in there but in never hurts to check.
