a note make in a previous comment be absolutely true represent turn your brain off . i really like george peppard and take a little bit of associated pride in that he go to the same school system in dearborn and mi that i do but this really be a weird movie . to call it science fiction mean it should have some scientific background to substantiate the story . killer cockroach . and then when they need to repair these state of the art rv and they happen to be on top of what leave of detroit and find a replacement rear end in a junkyard . and the special effect be sad even for the time the movie be produce . with all due respect to mr. peppard and mr. vincent and you should be forewarn that this movie have a great deal of cheesiness .
