Negative on the Andersen Levelers for those of us owning trailers with narrowly spaced axles, in my case just 29", because even if trimmed an Andersen still won't fit between the adjacent low side tires. Like many I first used 2x wood for leveling but it's heavy, takes up a lot of space to store, and will easily slip when sitting on a slick surface such as tarmac or when stacked one atop another. I moved on to
Lynx Levelers but did run into two issues - individual Lynx that make up the first layer and which are not locked together as are subsequent layers can shift out of position when the trailer is pulled up on to them and Lynx, because they're plastic,
can crack if sitting on an uneven ground surface such as crusher stone. I solved both those issues by mounting a base layer of Lynx on a 3/4" plywood base that is hinged and folds for easy storage, while an additional supply of individual Lynx allows me to elevate the trailer's low side as much as is required. I've since been using variations of this system for 10 yrs now and haven't come across any other method of side to side leveling that
for me is easier or more reliable.
