  • Perfect height and good quality for my camper
Color: 578H-6''H 1PC
Perfect height with just the one. Sure beats piling wood blocks underneath the jack. And it looks a lot cleaner. Now I can leave the camper at the right height every time. Seems pretty sturdy, feels nice and solid but not too heavy. Good price. Arrived quick and I like the storage bag so my stow compartment doesn't get dirty. ... show more

  • Great Stacking leveler
Color: 578H-6''H 4PCS
Space saver and Strong. Every ounce counts when traveling and these leveling blocks are just the ticket! The are sturdy under the leveling jacks on our Toyhauler and stack and pack away into a storage bag using minimal space. They check all the boxes we needed for camping.

  • Working as expected!
Color: 578H-6''H 4PCS
They appear to be holding up well. Better quality than their competitors which didn’t last and they did not stand behind their product. It’s nice the way they stack and having a rope on them is a nice touch. They make the trailer more stable by eliminating 6” of the hydraulic legs sticking out.

Color: 578H-6''H 1PC
This is just what i needed for our RV. we used a block of wood before this, and it held water and would rot. this is lightweight, very sturdy and the perfect height.

  • Great Replacement for a Wood Block
Color: 578H-6''H 1PC
Very happy with the ROBLOCK 6” trailer jack block. It’s sturdy, lightweight, easy to position, and does exactly what it’s supposed to do. I’m especially glad to finally be rid of the bulky 4” × 8” wood block we’d been carrying around for our trailer jack. Cleaner, neater and much more convenient. Definitely recommend it. ... show more
