I have been wanting to buy a dump trailer but the more I think about it I have been thinking of buying a trailer with the roll off containers on them. Something around 16 foot so that I could use it for soil, mulch and convert it into a trailer to load leaves in during the fall. I could also drop a container off for a rental and dumping fee for someone to clean out a basement of for a construction site cleanup. Has anyone taken this approach and what are the pros and cons? The containers are not all that expensive.
