All the "gadgets" they sell for chocking wheels if one notices, are aimed squarely at the RV market. The other 90% of trailers on the road use either simple rubber chocks or lumber, bricks or rocks, etc.
It's akin to the wdh and sway control marketing. Sure some tow rigs and some trailers need help either due to payload capacity or the particular trailer loading, however they get sold as a "must have" and RV ers gobbled them up!
Semi trucks use air brakes which automatically apply and STAY APPLIED once the air has been removed from the brake cylinders.
RVs, not so much.
Does not take much of a slope for a RV to start moving.
With that said, I use simple yellow plastic chocks that can be found at any Walmart store and have never had any issue with any of my trailer rolling over those wheel chocks..
But that may be how I apply the chocks, I put one in front of the rear wheel and one behind the front wheel.. Then I drop a 2x6 IN BETWEEN those two chocks. This doubles the holding or gripping area under the chocks!!
I often see folks putting one behind the rear wheel then on in front of the wheel.. Doing this on damp or wet grass is an invitation for the chocks to slip since you now have much less gripping area under the single wheel chock.
