Leveling Blocks

2x10 is stronger and cheaper. Levelling blocks are much lighter and easier to store (and no slivers). I use a mix of both.

I tried using them many moons ago, and find lumber still works the best (for me). Yes, lumber is heavy, and takes up space... yes! But it works for us. The Lynx blocks are hallow, and if using them on sand, grass, or dirt, the edge on the back side will sink into the ground until the ground touches the underside. So, actually, the first layer is a loss, but necessary on sand and dirt.

Not to long ago, someone said on these forums that the plastic Lynx blocks get misshapped after a while. Because they are plastic, I can see them eventually breaking. I've been using the same treated lumber and posts from a 150 year old bar under my jacks ever since I had my first pop-up. Same boards. I paint them different colors every couple years. They are now currently red. Easy to see in grass or asphalt, and never forget to get them or leave them behind by accident. Also, 2x4 x 18 inches comes in real handy for leveling picnic tables. Nothing worse than have your eggs slide off your plate on an unlevel picnic table. So I carry a lot of lumber for all kinds of stuff. I've go no problems stacking lumber up 9 inches or more high to level one side, if the camp site is that unlevel side to side (which.... we've been to a few like that over the years.) Lumber is MY friend!

I have a set of yellow Lynx in my pass-through, but never use them. Been dragging them around for years too. Maybe someday my wife will let me get rid of them.

Folks either love the Lynx and swear by them, or they hate them. Seems to be no in-between opinions.

We use 2 sets of them yeller squares. You can stack'em into pretty high pyramids when needed.

I have a mix of 8-4x6x12" and 4-3/4"x12x12 plywood screwed together and 20 yellow blocks sometimes had to use all of it

Just used a few of my blocks the other day, had not used them in a few years though. Needed to put the left side up just a little, they worked.

My concern about the yellow blocks is that they may not support the entire footprint of the tire. When that happens the load is taken by only part of the tire possibly overloading the tire. Just overnighting? should be no problem. However, if that condition exists every time out it could be a problem.
We use 2 inch thick boards several inches wider than the tire. That additional width also make is easier to drive onto it.

Much prefer my Wood / Lynx Leveling System that I've been using for years ... folds in half for easy storage, doesn't sink into a soft ground surface, and the wood base has eliminated any chance of Lynx breakage. Some of my Lynx are now 15 yrs old, a little faded but otherwise the same as they were when new.

We use the same, a mix of both.

I've used the same 20 orange blocks for over 10 years and they are still in good shape. Never had an issue getting the tires completely on the blocks.

I once got my truck stuck with the 5er attached. Sunk the front axle in soft dirt/mud. Put five of them behind each of the 4 rear tires and backed right out.

I used the level blocks but retired them in favor of the Andersen Levelers. The blocks now get used exclusively for the stabilizer jacks and the tongue jack if needed.
