I'd be curious to know how this story ended.
I'm also curious as to the proper part number for a new thermostat for a Marauder. I have heard RT1110 is the latest, I've also heard RT1196, RT1234 and RT1085. The funny part is, they all look different. So one has to be right and it would seem getting the right one is critical. Man my 2V was way easier...
