I found a truck in a yard that has a excellent bed but has been it hard in front of the rear wheel. This thing has NO rust orig paint perfect cab corners rockers and wheel openings. He said for under $100.00 I can cut off what I need. If I buy a 18V dewalt cordless sawzall will I be able to cut all this off? I also thought of bumming a generator and using corded power tools. I hate to see this get crushed infact he said he would wait till I was done. I have never done anything like this.
