Review on RVMATE RV Leveling Blocks: 10 Pack Interlocking Pads with Storage Bag & Heavy Duty Design by Johnny Moger

I like them so far but they have limitations. You are fragile. I don't know if they break on soft ground. I'm new to trailer leveling and have used some curved cam levelers. I needed more height than the cam straightener could provide, so I had it roll onto one of these blocks. A hard, narrow cam broke through the block. I think I could have avoided damage if I had used some 1x4s to smash into the block. If I hadn't used cams, the soft tire wouldn't have destroyed the block. You will probably need more of these than you can imagine. In some situations you can easily use the kit under the tongue, and if you have double axles then in many others.
