Is there a good way to transport a golf cart with a 5er?

I too am facing a similar issue, with the desire of transporting a 1200# four seater Polaris. Currently, the thought is to use a dual swivel wheel trailer, that's six feet wide, hence no trail over. The swivel wheels offer a locking feature that fixes them in a straight line with the truck, and then use a single point hitch and coupler, thus converting to a standard configuration.

Another concern, is how the additional weight to the real of the 5er impacts the pin weight.
