Camco 44432 Wheel Chock Without Rope, Helps Keep Your Trailer or RV In Place (Pack of 1) , Yellow

does the job.

Light weight. I use these for my airplane

Per another reviewer: AN EXPIRATION DATE?!?!? Give me a break. Mine arrived Dec 2012 and they expire Jul 2016, so I at least have 3.5 years to enjoy my purchase. Perhaps the resin gets brittle? Perhaps thats as long as the lawyers wanted to wait for a suit? They are also placarded (and, to be fair, noted in the description) to be used with 29 tires max. Fine for cars and trailers, not usable for motorhomes which will typically start at 30 and go up from there. The tight curve of the chock means that the larger tire, even a 30 or a 31, hits the TOP of the chock first; and this chocks hard, slick plastic will not grab a surface like concrete or asphalt, so the tire just pushes the chock along. Too bad really, because its a really beefy chock with a great ergonomic design, allowing you to easily grab it for insertion or extraction. Sad to say, I dont think the basic purpose is functional.

First time I used them, I managed to pull one of the ropes off because the chock was stuck under the wheel. Other than that, theyre great.

These work good with the rubber ramp I bought and the price if right.

No problem. I use it to hold my dump trailer when I detach at night. Weighs roughly 10,000lbs.

Ease of ordering

Nice chocks. Bright yellow so you dont forget they are there and a nice rope to pull them out.

They do what they were made to do.
