We needed a trailer we could haul behind our 35 ft. RV to pull our car along with us on long trips so we shopped around and found a trailer that was easy to drive up on. It is the tilt trailer - the deck tilts and you drive on!
It is so much easier to use than the kind with the just enough room for the wheels that you have to worry about rolling off the side of. And it comes in many different sizes in case you only need one for a motorcycle or ATV. You can see car trailers here. If you are looking for an easy to use car or motorcycle trailer this is just what you've been looking for.
