XSTRAP STANDARD Wheel Chock Non Slip Base, Suitable for Most Tyre Sizes, Ideal chocks for RV, Trailer (10" x 8.2" x 5.5"), 1 PC

Seems like a very nice, large chock. When I purchased it I thought there was two of them which seems logical since they are used in pairs. Plus the description refers to it as a “pack” which to me means more than one. After receiving one I read back through the ad and it never says there are two. So now you know.

We're using these on our tandem-axle travel trailer. They've performed well so-far. We did have one shatter like glass in sub-zero temperatures so be cautious when using them at extreme temperatures. They are wide enough for normal RV tires and have enough grip to prevent them from slipping out from underneath the tire when under load. Happy with them so far but I may add a small rope to use as a pull-string.

Had to lift the front of my CRV for an oil change, and these worked great, providing a good bite/grip into the gravel of my driveway.

It does not nest so storage is more bulky but it is sturdier because of more ribs under the ramp. It is light and easy to move around.

They do not hold firmly and scoot on the floor

Works for what it is needed for

Strong and lightweight. Easy to use and store. Not sure I would use with heavy trailer or if parked on a steep incline, but great for parking the trailer in the driveway.

Bought one as a test because price/features worried me it would be cheap and flimsy. It is not. Will be ordering more before hitting the road for the winter snowbird season.
