Here's a pic of our trailer. Really quite simple and transports up to four Hobie Outbacks very easily, tool box just adds another level of storage. Another nice thing about using a utility trailer with 14" tires is the trailer is doing about the same speed as your vehicle instead of the vehicle doing 65mph and the trailer doing 120mph with 8" tires
...sorry for the two "peoples" in the way but this was the only photo I had available. Was in a similar predicament as you with having to use the trailer for actual "trailer" use but made this simple mod to transport the yaks. Used it today and it just reminded me again how nice it is...hope this helps!
