Every now and then I see a 5th wheeler with a tripod under the pin, apparently for added support. Does this really do anything? The trailer sits on the wheels, the landing gear and the rear levelers?
I have used the same one for 10 years. It is no problem for me to set up and take down.
The tripod doesn't do much for rocking. However, I can only guess how many times someone would have bumped their head ect into the hitch. I also like the piece of mind knowing it will also support the front of trailer if necessary. I also lock my bikes and valuables to the tripod.
