I just purchased the R7111 . I wanted a drill that had enough torque to be able to raise up my tent camper. After trying out several differant manf. This is the only drill that would do the job. My question is I really wanted a Hammer drill, R5013 Do you no if the R5013 would perform as good for my purpose as the R7111. And still give me the added advantage of having the hammer drill.
