On Masterlock's web site there is a report called "Towing Troubles - Danger on America's Road". Here is a summary of the document. You probably had no idea all this was going on! The site this summary comes from is mentioned at the end of this blog.
What Are They Towing?
• Most Americans tow using a pickup (57%) or a sports utility vehicle (31%)
• Some 10 percent of respondents were towing with a vehicle that was ranked only moderately or poorly appropriate for the class of trailer they were towing while 10 percent did not have the most appropriate towing vehicle for the type of trailer they were towing
• A majority (80%) use Class III trailer hitches
Where Are They Going?
• More than one-quarter of respondents (28%) traveled between 50 and 100 miles, while nearly half (47%) traveled more than 100 miles to their destination towing a trailer
Their Negligence is Showing
• A majority (51%) of Americans who tow do not use the recommended security methods of a locking device for their coupler and hitch
• Nearly 50 percent (48%) of respondents towing boats use only a non-locking receiver pin to connect their trailer, which is susceptible to tampering
• Respondents towing campers had the best approach to safety, with 69 percent using both locks and pins to secure their vehicles, 69 percent using weight distribution systems, 71 percent using appropriately crossed security chains and 52 percent having a properly leveled trailer
• Nearly 50 percent (47%) of those towing boats didn't properly cross their safety chains under the coupler.
• A majority of respondents towing boats or ATVs/jet skis/motorcycles achieved a moderate or worse ranking on the levelness of their trailer. For ATVs/jet skis/motorcycles, 15 percent were ranked poor or extremely poor
• More than 50 percent (53%) of towing vehicles and trailers received only moderate or poor rankings on their electrical systems. Boat trailers presented the greatest danger, with 17 percent of their electrical systems in poor or extremely poor condition
• Trailer tires are one of the biggest dangers on the road, with 41 percent of tires in only moderate or worse condition. Some 10 percent of boat trailers had tires in poor or extremely poor condition.
Their Cargo is Overflowing
• Security of cargo on the trailers also is an issue, with more than 54 percent of campers, 28 percent of ATVs/jet skis/motorcycles and 49 percent of boats ranking as moderate or worse in their cargo security
• The security of additional cargo – loaded in the boats or campers – was a significant issue, with 32 percent of respondents ranking moderate and 40 percent ranking poor or extremely poor. This means coolers, lawn chairs, bicycles, and other typical cargo could easily fall into the path of an oncoming car
• The condition of bungee cords was a major issue – 46 percent were in moderate or poor condition and improperly located – meaning cords could easily snap or come unhooked and release cargo onto the roadway
• Ratchet tie-downs were a problem for 39 percent of respondents, as those towing boats or ATVs/jet skis/motorcycles received moderate or worse marks for the condition and location of the tie-downs securing their cargo
