WOW I'm ABSOLUTELY AMAZED at what appear to be the # of misinformed and clueless folks that have made this one line recommendations for these inbetween chocks like the rotochock, bal/X-chocks that even the manufacturer recommends against securing the trailer with as SoundGuy has pointed out.
I'm also amazed we don't read of more catastrophic stories when some of these safety devices are so misused.
For 40+ years I've used the run of the mill plastic yellow chocks and never had any issues except the couple to times I forgot to remove them and "crushed" them when leaving a camp site.
