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

El Dorado would be a Class C; Dodge Sportsman is indeed the generic name for that chassis. Your Dodge VIN number will tell you what actual model chassis you have. 383 is a great motor. I briefly had a 19' El Dorado with a 360. It had been partly gutted, so when I found the Concord, we sold it to a mechanic who needed it to sleep behind his shop during the week.

Somewhere on my computer upstairs I have a scan of the layouts; I'll see if I can find and post it tomorrow.
