OX BLOX MAXX Heavy Duty Trailer Jack Block - 10.5x10.5x4.5 Inches - 6.8 lbs Weight - 5th Wheel RV Jack Block for 9" Round Feet - 9" and Smaller Feet Nest Securely Within Ridges

My wife and I have a 43’ Sierra Luxury 5th wheel, our 2nd RV, but 1st 5th wheel. I researched best pads and such and have used all the normal stuff out there. I saw a video on YouTube where a person built blocks much like the size of these and I was set to do that. I priced everything out and was ready to go. My wife surprised me literally the day before with these just so I wouldn’t have to spend time going and gathering all I needed to build them, be in the summer heat of south Texas🥵, and miss a day on the lake with her. Well, to her, I say thank you. These are great! . They are durable and easy to place. Storing isn’t horrible, yes they take space but if you RV, you understand what your trading when you use a product like this. I have 4 of these & 2 red buckets (typically use for the front). I can switch around as needed and have. I 100% see the value in these and definitely recommend these!

Sure you can use stacked wood- but it cracks and splinters- not too mention it looks trashy. I tried a full set of yellow jack supports from a “Large Camping Store” they were not up to the job. They were too tall for stabilizer jacks and split dropping my tongue jack to the ground a waste of money.Enter OX BLOCK MAXX-They are stable, Criss cross reinforcement on the base will not break under tongue jack load. The height is perfect at 4.5 inches for stabilizers and interlocking stack of two for the tongue. The finger holes are a great touch.If you can get over the cost the function is top notch. One tip would be just buy these and skip the yellow ones that will save 150 bucks!

I've been impressed considering it is a block. I have had them a little of over a year, used frequently in the winter, and they do the trick with no signs of breakage.

Only used once so far but I wanted to review since there were so few written. It is definitely sturdy and I'm not worried about them breaking at all. I previously used cut pieces of redwood but those were beginning to crack after repeated use. These will slide on wood so just know that you probably shouldn't put these on top of wood. But, they are tall so it replaces two of the 2x's that I was using before. Going to buy a few more so I can stack them if needed. Only issue I had was that I didn't quite line up one of them with the jack. It was the opposite side from the landing gear control so I didn't notice it until I was already unhitched. No big deal, just caused the foot to flex a little while the weight was on it. Now I understand why the other brand puts magnets in theirs, but these may be too well built for magnets to work! Not that they are heavy, as they are not.

Absolutely perfection.Completely indestructible.Even drove my RV onto them in order to escape out of a beached RV situation.I WISH THEY MADE RAMPS TOO!!!

The media could not be loaded. I really liked the great design and how sturdy they make our camper. The blocks come with finger holes for carrying them. A rope can also be used in the holes to make a handle to carry the block. I choose to lock some of my blocks together as you will see in the video. I used a piece of sand paper to break the inside edge of the hole which has a very square shoulder on it. I would highly recommend that anyone interested in buying these blocks go to Ox Blox website to research which blocks they need for their rv. I did a very nonprofessional video that I hope might help new buyers.

We recently traded in our travel trailer for a 5th wheel and I wanted blocks to put the leveling jacks on to prevent concrete staining and rusting of the jack pad. I came across these and since my rig has 6 leveling jacks that the 6 pack would be good. Great price comparable to what some of the other competitors had (these were less expensive😊) and they had a load rating of 10k pounds each (not that I have 10k lbs at each leveler) I figured they would hold up. So far I haven't been let down.

Works great for the trailer stand. No more trying to look for cinder blocks. This is supporting my 26ft boat trailer perfecty fine.
