Camco 44505 RV Leveling Blocks 10-Pack | Interlocking

Nobody sleeps well in a camper that's leaning. Your fridge doesn't run right, the shower drains to one corner, and you spend the whole night sliding toward the low side of the mattress. That's what the Camco 44505 leveling blocks fix. It's a 10-pack of interlocking plastic blocks you stack under your tires or jacks to bring the rig level on an uneven site.

Here's how they work. Each block is 8-1/4 inches square and 1 inch tall, with an interlocking pattern molded into the top and bottom. You snap them together into a ramp or a stack, drive up onto them, and stop when your bubble level reads flat. Because they lock together, they don't scatter or kick out from under a tire the way loose boards do. And because each one is only an inch thick, you get fine control over the final height. One block on the low side, or five, whatever the site demands.

The set is rated to 4,000 pounds, so it handles travel trailers, fifth wheels, truck campers, and most single or tandem-axle rigs without complaint. The blocks are molded plastic, so they won't rot like plywood, splinter, or soak up water on a wet pad. Hose them off, shake them dry, and drop them back in the included storage bag. That bag is a nice touch. It keeps all ten together in a basement bay instead of rattling loose in the truck bed.

We reach for these in a few situations. Gravel campsites that dip toward the fire ring. Concrete pads poured with more slope than the builder will admit. That one relative's driveway you park in every Thanksgiving that's never quite flat. You build a short ramp on the low side, pull forward until level, then chock the wheels and set your stabilizers. For side-to-side leveling, stack under the tires on the low side. For front-to-back, work the tongue jack or the landing gear onto a stack.

A few honest notes from experience. Stack them like a pyramid when you need real height. Widest at the bottom, narrower as you go up, so the load sits square and the tower doesn't lean. Don't build a tall skinny column and drive a loaded trailer onto it. On soft ground, gravel, or sand, lay a piece of plywood under the bottom layer so the whole thing doesn't sink and undo your work. And check the interlocking tabs now and then. They take real load every trip, and a cracked tab is easy to spot and swap out from your spare blocks.

They pair naturally with the rest of your setup gear. Use them with wheel chocks so nothing rolls once you're level, and set your stabilizer jacks or tongue jack on a block or a small stack to keep the feet from digging into soft ground. The 8-inch square footprint sits nicely under a standard jack foot or a tire, and the flat, textured top gives a tire something to grip instead of sliding off.

Ten blocks is the right count for most single-vehicle setups. It gives you enough to build two decent ramps at once, one for each side, with a couple left over. If you tow a longer fifth wheel or you camp somewhere genuinely steep, a lot of folks keep a second set in the bay. They're light, they stack flat, and they store small, so carrying spares costs you almost nothing.

Bottom line, this is basic gear that earns its keep every single trip. It's the difference between a camper that feels like home and one that reminds you all night that you parked on a hill. For the money, a set of Camco 44505 blocks belongs in every RV storage bay.
