I have an 18 foot car hauler (16 foot with a 2 foot dovetail) it has two 4 foot stow away ramps which are nice but in order to clear the front bumper I had to build 2 additional 4 foot wooden ramps (easy to do). I went with a big tex trailer with tandem axles and brakes on both axles. The only thing I would change about it if I could is the height of the fenders. I can't open the doors very much on the Z since the fenders are so high on the trailer. It makes it kind of a squeeze getting in and out of the Z's.
