I already had two sets of levelers that came with our used motor home. There are caps in those old sets. Maybe the previous owner bought them separately; I don’t know. It seems to me though that they complete the set and should be included so that buyers feel like they are getting all that they need and not have to buy more parts and pay more shipping. Otherwise, a good product.

My granddaughter had these for her RV. I swiped a couple to use as a monitor stand as they fit perfectly for my old plasma TV. I bought a set of my own to use for leveling my temporary greenhouse. They provide a very stable platform. I am sure I will find many other uses for them. They also came in a very nice carry/storage bag which is great as well. I highly recommend these for RV's, trailers, as well as many other applications where leveling is needed.

We bought Lynx Levelers when we bought our trailer and just bought another set, after experiencing an unusually sloping campsite. I love that I was able to buy only six and they fit perfectly with our original set of eight.
The price was also right!

A must have for any RVers

I love these stackable 10 packs .I have a 2400 lb camper and it's the off-road edition which means it sits higher than normal. These blocks work for stacking together to level it up for use under the tires and I use them under the jacks for support. Bright orange color is excellent and makes it easier to find and stack when sitting up in the dark and making the corners easier to see in the day when walking around the camper. I wouldn't use anything else!
