Camco 44652 RV Wheel Stop for Tandem Tires

If you've ever tried to relax in a tandem-axle travel trailer only to feel it shift and rock every time someone walks to the fridge, you already know the problem this little yellow block solves. The Camco Small RV Wheel Stop wedges in between the two tires on a tandem axle and locks them together, so they can't creep back and forth against each other. Less tire shift means less of that rocking you feel inside the camper. It's a simple piece of gear, and it does one job well.

Here's how it works. On a tandem-axle trailer, the front and rear tires on the same side sit a few inches apart. That gap is where this wheel stop goes. You slide it into the space between the two tires, and its raised rib surface bites into the tread on both wheels at once. Once it's seated, the tires can't roll toward or away from each other, which is what causes most of the movement you feel when you're parked. Grab the built-in rubber handle, push it home, and you're done. Pulling it back out when you're ready to hitch up is just as quick.

Fitment matters here, so check your tires before you buy. This model is sized for tires between 26 and 30 inches in diameter with a gap of 1-1/2 to 3-1/2 inches between them. That covers a big chunk of common travel trailers and fifth wheels, but not all of them. If your tires are bigger, smaller, or spaced differently, measure first. A wheel stop that doesn't fit the gap won't hold, and one that's too big won't seat at all. Measure the diameter of your tire and the clear space between the two treads, then compare against those numbers.

A quick word on what this is and isn't. This is a stabilizer, not a substitute for chocking your trailer. It keeps the tandem tires from shifting against each other, but it does not stop the whole trailer from rolling on a grade. Always set your standard wheel chocks and your parking brake first, get the trailer leveled, and then drop this stop in between the tires as the finishing touch. Used that way, it's a great addition to your setup. Used as your only means of holding the trailer, it isn't enough, and we'd never tell you otherwise.

The build is straightforward. It's molded from a high-strength, lightweight polymer, so it shrugs off sun, rain, and road grime without rusting or rotting the way some gear does. It's light enough to toss in a storage bay without a second thought, and at roughly 17-1/4 inches long by 5-5/8 inches wide by 2-1/8 inches tall, it tucks into a tight compartment easily. The bright yellow color isn't just for looks either. It's easy to spot in a dim storage bay and easy to see between the tires so you don't drive off with it still in place.

This one is sold as a single unit. If your trailer has tandem axles on both sides, and most do, you'll want two, one for each side, so plan accordingly. A lot of RVers keep a pair in the bay and set both any time they're parked for more than a quick stop. The rubber handle makes placement clean even if you're reaching down between dual tires, and there are no straps to ratchet or tools to fumble with. Slide it in, snug it up, walk away.

For weekend campers, snowbirds parked for the season, or anyone who just wants a steadier trailer at the campsite, this is one of those small, inexpensive upgrades that punches above its price. It won't make headlines, but you'll notice the difference the first evening you spend inside a trailer that isn't rocking every time someone moves around. Pair it with your chocks, level the rig, and settle in.
