Strickland Propane is a fictional propane and propane accessories supplier in the animated series King of the Hill. Buck Strickland owns the company, headquartered at 135 Los Gatos Road in Arlen, Texas, though he delegates most of the day-to-day responsibilities to his 41-time employee of the month, assistant manager Hank Hill. Sometimes Buck is seen at Strickland headquarters, but he spends much of his time with his mistresses and otherwise enjoying himself around town.
