Had this problem too. Told DH, he got a smirky smile on his face, went out to his truck, rummaged around behind the seats in the extended cab, and brought in a small all-rubber car mat that was under all his tools and stuff. Car mats were put in there 9 years ago when he bought the truck, but no one has ever sat in those jumper seats. Foot pedal never moves now. He's always thinking of ways to help me out with my Expensive Hobby.
