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

My contractor lives in a 73 Dodge MH with a 360 and the 2245 Holley. I was wondering about that on his, too (I looked at it to see what's wrong since it quit running after the last parking, the float is stuck and flooding everything out). I would assume his has no guts uphill, whereas I can definitely hear the secondaries kick in on mine going uphill or leaving the stoplight briskly.
