The only equipment I rent out is a skid steer with operator included.
In my area a skid is $275 a day and attachments are $200-$250 a piece. Delivery/pick up is another $100.
So I deliver it, my guy operates, then I pick up for about what the rental yard charges. The main reason I started doing this is because I have no need for 2 skids 7 days a week.
