How many of us are there? Owners of Dodge based RV's?

Hi, thanks for all the great idea's. So far I have flushed the radiator, all belts and hoses are good. I am in the process of adding a Transmission cooler today, have blown out the radiator fins and moved the front lic plate which covered about a 2" x 10" part of the lower radiator. I'll let you know if any of this helps. If not my next two items to check are the fan clutch and radiator core.
