Old Cult Movie

[Roper]

I need some help.  I am looking for a movie from the 70's or 80's that I saw on TV a couple of times.  It was about these two couples in a recreational vehicle on vacation somewhere, I think, out west.  They are being followed by a cult or something and at the end of the movie they are caught in a circle of fire.  I can't remember alot about it, but would like to know the name of it.

PLEASE HELP

Thank You,
J

This sounds like it could be the 1975 flick RACE WITH THE DEVIL. You can read more about it at:

That almost definitely is "Race With the Devil.”  I knew that one.  Beaten again.  Curses.

I'd have a guess at that being "The Hills have Eyes" (1977)
I could be wrong though.

Basic plot:  A family going to California accidentally goes through an Air Testing range closed to the public. They crash and are stranded in a desert. They are being stalked by a group of people, which have not emerged into modern times.

If the two couples are Peter Fonda and Loretta Swit and Warren Oates and Lara Parker, then the film is indeed "Race with the Devil." Two couples come upon the inhabitants of a small, Texas town practicing human sacrifice. (Isn't that way with all small Texas towns?) All the inhabitants of the town are Satanists, even the town's librarian. For personal reasons, that one always leaves me ROTFL. Actually, shot in central Texas. Enjoy!
