Trailer Jack Block, New Version RV Camper Blocks for Travel Trailer 5th Wheels and More, Up to 15,000 lbs, Use for Any Tongue Jack, Post, Foot, 5th Hydraulic Scissor Stabilizer

Purchased this for our travel trailer to replace our original jack block, which d/t convenience and necessity was a large and heavy cinderblock. This works perfectly, strong, stable and much lighter. The recessed area on the top allows our jack to set securely.

Use this for 8k pound toyhauler tongue jack. Felt it was a bit high at 30 for it's use, but now that I have it I say totally worth it. Pretty heavy, feels really sturdy. They don't show the underneath in the pics but there is a lot to it under too, very solid, strong. Little holes to put your fingers into to pick up, but if you're like me and not a fan of spiders I suggest you pick it up some other way.

I bought two of these to replace the pieces of wood I’ve been using. They are neither light nor flimsy. They are built solid and I have them holding up the front of my 34’ travel trailer. Depending on how level an area you park on, you could probably get away with just one block, but I bought two because when boondocking you usually don’t get nice level surfaces. They stack nicely together and come apart just as easy. I’m not sure why I didn’t buy these years ago, but I’m glad I have them now. Definitely worth the money and easy to store in my truck bed.

better than carrying multiple pieces of wood, very sturdy but a little on the heavy side. They are stackable, good for stabilizer legs or tongue jack (just make sure the steel washer is in the hole as I got one it was missing in)

Solid for trailer hook up

I have been using these blocks on the front of my 5th wheel for about a year now. They are always under the 5th wheel - rain or shine. I am impressed by the structure and sturdiness, but after being out in the weather for the past year have become brittle. A couple of the small centering tabs on the tops of the blocks have broken off. I am still using the blocks but will replace soon.I gave them an overall rating of 4 stars simply because of the broken tabs. For the price, I would have expected them to last a little longer. Having said that, I will probably buy another set of these blocks and move these to the rear stabilizers where they aren’t under as much stress. While they aren’t perfect, I would still recommend.

I was surprised by its weight. It was sturdy and works great.

This thing is very heavy duty. It is rather heavy for a peice of plastic. It should last for a long time and I have no worry about it breaking. There are several ribs on the underneath of this thing and should support anything.
