Stackers Blocks and Chock
Stackers leveling blocks can be stacked directly on top of each other for supporting a trailer tongue, or you can stagger the blocks to create a ramp. Not only do the individual raised squares interlock with those on the block placed above it, but the built-in handles also interlock with these squares for a more sturdy and streamlined design. The Stackers chock (A10-0922 - sold separately) can then be attached to the leveling blocks to help stop your trailer or RV from rolling off the Stackers.
Ratings & Reviews
Had two bundles of 10. Added the third. We used them at the base of steps to make a safe landing area when stepping of of our fold out patio.
These are a great product as opposed to caring blocks of wood .durable ,stackable and comes in a convenient carrying case.
Arrived quickly. They're exactly what I was looking for at a very good price. Light weight and easy to place. The handles really help.
fast shipping and products as described, great company will use in the future and have already told friends.
These stackers help with setting up the camper much easier
The items were delivered today as tracking showed the name was wrong my name is Delbert the packages were addressed to my wife Eileen I suppose it was a honest mistake but the products look great and will work perfectly for our trailer. Thank you
These stackable leveling blocks worked as advertised.
Everything was a quality product,the Hopkins leveler did get damaged in shipping by the shipper , Customer service to care of it immediately without any issues,I received it today and everything works,thank you Melisa for all your help
Excellent product and the service from etrailer is top notch. Will continue to purchase from them always.
Two items in this order were defective, etrailer made it good immediately. I was surprised to receive a new part that I had forgotten I talked with CS about. This company never forgets, stands by their word. Excellent
Very well made, will be used to interphase loading a Porsche into a trailer to raise the angle of approach in lieu of wood blocks. Also to be used to firm up our auto leveling studs in our Airstream Interstate 24, so they help by not sinking into the ground.
The stackers we purchased from etrailer were just what we needed to level our food truck on slightly uneven surfaces. We appreciate great products and service too! Etrailer provided both! I will definitely purchase again!
These stow easily when not in use. Quickly assemble to level trailer. Easy to clean up after use. Ordering from etrailers.com hassle free and they keep you updated on your order status.
Great idea for "pre-leveling" our truck camper when the truck is on a slope, as is often the case in the boondocks. Makes it much easier for using the electric jacks on the camper. Well made and easy to use. I haven't had this much fun with building blocks since my first set of Lincoln Logs (way) back in the day!
etrailer has the best customer service in the industry--and no, I don't know anybody who works there.....
Leveling blocks work well. However, I did experience some light damage on the bottom block from the weight of my trailer and the rocks (larger gravel really) and now they don't interlock. My trailer weighs about 9000#.
If you are still using pieces of 2x6 to level your small camper, you need to pitch them and get these. They lock together, so if you're on uneven ground, you don't risk them shifting while you're trying to level the camper. Also, they don't retain dampness like wooden blocks. The bag even has a built-in vent so it can breathe if you have had to pull out in the rwin. Well worth the price.
Haven't had a chance to try them yet, but was extremely happy with the service at etrailer. Ordered later in the day and they shipped same day.
Everything came as described with no issues of damage. Electric jack was very easy to install. Towing mirrors are great allow me to see more especially when backing up my camper. Weight distribution hitch well without that I wouldnt have got my camper home. No sway issues, people have said its loud.... I didn't hear anything. Overall great products, fast shipping will definitely be ordering all my camper/towing needs from etrailer.com
I had 1 set of these. They work great. I just needed anther set for dually rear wheels on my new motor home.
Seem very heavy duty. Came in a nice carrying bag. Can't wait to go camping to use them.
Looks of good quality would buy again
Has lots of ways to level your RV like the case to keep them in order strong materials

Have used these Quite a few times and I was able to get a leveling solution each time the only issue I had is that one of the blocks warped I’m guessing because of the high temps we’ve had around 100 for several days
I think if you have extra money burning a hole in your pocket you should buy these blocks instead of getting slivers from your heavy wood blocks.
Fit perfectly and wires were long enough. Works as advertised.
These stackers are heavy duty enough for large, heavy trailers. They are quick and easy to set up when leveling our 42 foot horse trailer with 26 foot full living quarters.
Do you have a question about this RV Leveling Block?
