Owners of Dodge based RV's?We have a 1977 Lindy 20' perched on a Dodge B300 chassis with the 440 cu in motor and automatic transmission. She is currently undergoing a full mechanical service bow to stern. When we get her home we will probably add headers as I understand they increase horse power and mileage. Any other recommended changes?
