We recently purchased our 40 ft. '05 Monterey & love it, but not the rattle that I have finally located to be inside the entry door panel. The door otherwise works fine, but . . . the rattle . . . must be silenced! After removing the access panel to the latching mechanism, the lower part of a rod leading to the lower latch? moves freely inside the door panel and I believe it is disconnected (the noise is suspiciously similar to the rattle we hear while in motion!). While attempting to remove the door panel, I removed the inside window frame, but no cigar . . . the door panel will not budge! The only way to repair the lower latching rod assembly is to remove the door panel. Can anyone advise me what else needs my attention before the door panel is removed?? Any assistance would be greatly appreciated.
