Rophor 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 Jack or Scissor Stabilizer

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.

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

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)

Perfect height and very sturdy and made of good quality material.

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.
