9. Be aware that a turn for the trailer will be wider than a
turn for the tow vehicle (Figure 4-2). When making a
turn, be careful that your trailer does not strike another
vehicle or object.
10. Inspect your trailer regularly to make sure the side
supports are in good working order. Check bolts which
secure rollers and supports for tightness. Check wheel
bearings frequently for sufficient grease.
11. Check local and state laws for any additional
requirements for trailers.
