My sedan hauling my surron!

The hitch was put on by U-Haul and the adapter is a 4 inch rider 2 inch to 1 1/4 inch. The surron holds very well, no swaying or problems at 50 mph. Do you guys think the is a reasonable solution? I do not have a truck.. this is what I decided to do with what I already own. What you think?
