There was a pretty good discussion on X-chocks a coupla weeks ago, I think.

Hard to believe it's necessary to repeat ad nauseam as we did in this recent rv.net discussion that Norco's BAL X-Chocks, despite being called "chocks", are not intended to be used to secure a trailer to prevent it from shifting. Every box of X-Chocks includes a warning note to this effect so how anyone rely solely on X-Chocks as chocks is mind boggling. :S

My brother forgot his when he went to leave the campsite. Wheels were locked and they don't move... not sure how much more you need out of wheel chocks.

Clearly you (and evidently many others) still don't "get it". :R Tires shrink noticeably as they cool so anyone who pulls into a campsite, sets up, and uses nothing but X-Chocks to secure their trailer is in for a nasty surprise if there's any slope to that site. :E In the first couple of hours those tires will shrink, the X-Chocks (or any in-between tire chock for that matter) will loosen sufficiently to lose their grip on the tires. Installing X-Chocks before unhitching is also a no-no according to Norco as the tires want to rotate as the tongue jack is lifted / lowered during the unhitching / leveling process, resulting in undue stress being placed on the X-Chocks. This information is all contained in this manufacturer's warning note which your brother either didn't read or chose to ignore. :R

I'm sure that is nothing more than liability to cover the company's butt when someone doesn't tighten the chocks and the trailer rolls. Yes tires shrink and yes you should check the chocks. Properly tightened the trailer is not going anywhere.
