I can't find any info on it but it was called
Daddy's Girls. It was kind of a Dukes of Hazzard parody.
Pa (an old dude who looked like Uncle Jesse) has three hot daughters who all team up to help keep the bad guy (a Boss Hogg lookin' dude) from getting hold of their land. This of course involves fucking all of Hoggs henchman. Even at the time I wasn't quite sure how that's a bad thing for the guys but somehow they managed to save the farm.
I saw this in an actual movie theater back about '82/'83 when I was just 17 and had only seen hardcore pics in a magazine.
I still remember a lot from it.
