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

Thank you for your tips Griff! My play is not a rebuiling of the Thermoquad, but to eliminate the leak. I hope, it's only the gasket under the carburetor. Making photos is the first what i do :-) I know the problems from restoration of old 2 stroke scooters and there is everyting very simple.
Out of interest: What is the price of a Carter Thermoquad in very good (plug and play) condition?
