I have an idea, but I am not sure if it is feasable or not. just wanted to take your opinion. We got rear ended last summer and my wife still feels pain on her neck. We were "lucky" because the bumper absorbs the impact. Now after I install the hitch, the bumper wont be able to absorb the impact in case another idiot hits us. I read an article and a Government agency conducted a study and they prove that as well...the occupants of a car with trailer hitch is affected more compared to a car without a hitch. the only advantage is the affected car has less damage, but I dont agree with this statement. The hitch is attached to the frame and if hitch had an impact, the frame will be effected as well and I am sure there will be minor cracks on the welding points of the frame.,.anywayq, my idea is to remove hitch end of summer and install it back end of winter. just like the tires. I am using hitch for the bikes during summer, so no need during winter. by this way, hitch wont get rust and risk of being injured after a rear ended accident will be less. but I my concerns are:
-will the conical washers deformed after two, three times of tight-loose cycle?
-in the long run, will it damage the threads on the welded nuts? since the torque is high.
you know, you bring up a lot of interesting points. points that i myself have thought about for some time.
do i drive around with the ball & receiver in?
what if i get hit? will it effect the hitch? will it bend my so called frame? etc etc etc.
many good questions - to little science. but i think removing the hitch every few seasons just to reinstall - is kinda over kill. I dont think having a hitch will cause more impact or pain to the occupants, than the impact did on its own. if so, very minor. not worth the trouble.
MY THINKING OF IT IS: if the impact is great enough to make the hitch bend the frame, cause cracks, ; your car will be totaled insurance wise- so who cares. Any frame damage = instant loss.
