Finding the Right Trailer

Tips from Real-Estate-Agents.com

There are several different weight classes with maximum tow ratings. Some people still weld trailer hitches to the frame (which could possibly weaken the frame), companies that rent trailers also offer to rent or sell custom-fitted hitches that bolt to the frame and usually use pre-existing holes. Installing a hitch on your vehicle is an investment that increases your vehicle's utility value. Not only will you suddenly have the ability to tow trailers designed for moving, boating, biking, camping, etc., you'll also be able to attach a bike rack, ski rack and other accessories without clamps or straps that could damage your trunk or roof.

A compact car can tow with a Class 1 hitch. A mid-sized car could tow with a Class 2 hitch. Minivans can pull up to a Class 4. Full size pickups and SUVs can tow with up to Class 5 hitch. A mid-sized car might be able to pull the larger trailers locally if there are not a lot of hills. Although the largest trailers are rated Class 2 minimum, a full sized pick-up or larger vehicle is recommended for towing them long distances or fully loaded. The size of the trailer needed depends on the amount and type of items to be moved. The following is a general rule of thumb:

Car top carrier:

Up to 20 cu. ft. May be attached to any car that has a rain gutter at least 24" long (which includes most passenger cars).
4' x 8' trailer; up to 142 cu. ft.; hitch required: Class 1 min.
5' x 8' trailer; up to 208 cu. ft.; hitch required: Class 2 min.
5' x 10' trailer; up to 230 cu. ft.; hitch required: Class 2 min.
6' x 12' trailer ; up to 396 cu. ft; hitch required: Class 2 min.
Not all trailer rental locations install hitches, so it may be advisable to have a hitch you are buying installed ahead of time, or plan ahead to have a rented hitch installed early on the day you plan to move.
