Whether or not the switch is beneficial is a matter of luck when the trailer becomes unattached, and where other cars are situated.
A trailer suddenly stopping will wake up the following drivers in a hurry with no brake lights
Likewise a trailer zigzagging across the interstate at full speed would not be the best thing either.
The best medicine is to keep your coupler in good shape, adjusted and double check your actions when hooking up.
If the whole front A frame breaks off the trailer the battery
will likely be disabled and the brakes
won't function. Periodic inspection for cracks in that area would be a good idea. Look for rust lines on the painted surface.
Some manufacturers use a simple butt welded miter joint at the A frame junction with no fish plate reinforcement. Pretty iffy....
Good post. Lots to think about here. Then there is the do you make the switch activate before or after the safety chains are engaged
discussion. A search will yield arguments for each. I made mine the last line of defense and hope it's never needed.
One other point. I some how had mine pulled while camped. I dont know how it happened but the battery
was dead by morning. Now I check it as part of setting up.
