The reason you were referred to Rush Ford is because they are a Med Duty Ford Truck dealer. Galpin is a Ford car dealer.
I take my MH to Rush Ford Med Duty truck dealer in Denver CO and yes it is a 35-40 mile drive for me.
Or as one poster said try Fairway Ford or Giant RV both of which have good reputations.
