Thule trunk racks fit as well as their roof racks. The construction of the racks is also first rate. Everything from the rubber bike cradles to the sturdy steel frame is of the highest quality. Hitch mounted bike carriers are available for every type of hitch. The advantage of a hitch mount rack is that the hitch carries the weight of the bikes not the car's trunk or bumper.
Nothing rests on the car's finish to mark the paint.
The down side is that most hitch mount racks don't allow you to pull a trailer and use the bike carrier at the same time. The Trace bike carrier, however, allows you to use both the bike carrier and the trailer hitch. The key is Trace's unique mounting bracket which sets the bike carrier beside the hitch ball. This also allows a ball hitch carrier that is easily removed when not in use. A great accessory for any trunk rack is the Trace Tie Down Strap.
