Straightening truck frames is a very dirty job. It's physically difficult (you must have some muscel), takes some brains (not everyone has them), and you have to not be afraid to get down and roll around in the dirt and grease. It't hot and sweaty and dirty in the summer and cold and dirty in the winter. It might make an interesting segment. Thank you, Marcia Delehoy Paul Lucht and Son's Inc 402-3420-5630
