Interesting leveling blocks

way too complicated for me. Prefer to use correct number of lego blocks (prefer the yellow kind). Don't like green either.

Not sure what system you're referring to as "way too complicated". :h The problem with any brand of plastic "lego" blocks is they can shift out of position when you pull the trailer up on to a single layer because the blocks are not interconnected as they will be if using more than more layer. Individual blocks can also sink into a soft ground surface such as sand or mud and they can easily crack when sitting on a rough surface such as crusher stone or on an uneven surface which doesn't properly support the block(s). Securing a base layer of these plastic blocks to a wood base solves all these issues. TriLynx could solve this with their Lynx leveling blocks by offering versions with molded on bases in 5, 6, 7, 8 block configurations, as I suggested to the company years ago. Unfortunately they don't, so my solution was to DIY my own using the next best thing for a base - 3/4" plywood. The original version I built years ago for our 2007 TrailCruiser used a single base 6 Lynx long but I later hinged the base to halve it's length and thus make carrying / storing much easier. There's nothing complicated at all about it. :B
