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

Ain't we havin' fun?

Truckers use "reefer" as well as boaters.

And, many people, in all occupations and activities, use "reefer" and "refer" interchangeably. "Reefer" was more common for non-tobacco smoking material ... not to be confused with "kinnikinnick," which was used by some elders who were influential my upbringing.
