Quite a few years ago (and 3 rv's later!) we went with Lynx Leveling systems blocks...the ORANGE ones. I've "been there done that" for many years with scraps and hunks of wood...and after accumulating several sets of Lynxs blocks...I can level my Jayco RV, change the oil on our cars...all without splinters, slivers, jacks sliding off and spiders!
And unlike the "wood blocks are great guys"....if you ever have any issues or problems...the Lynx guys are supurb with customer service. At a RV trade show I mentioned to one the owners of Lynx that I needed a new carry bag for one of my sets.
"Lance", the customer service manager took my info and sent me a new carry bag..complete with another set of blocks! Cool!
