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

Our coach is a 1974 Dodge Fireball, 24'. 360 motor. We replaced all the carpet. reupholstered the couch, replaced the mattress, rewired the lights, rebuilt the motor, trans, rebuilt the carb, window dressing etc. We get 13mpg on the road at 55 mph.
It's called the party model as it is open all the way back, makes it look a lot larger then it is.
