Last year we put a big metal level on the frame, just in front of the propane tanks. It is zip tied on, and it works great to show what side needs to be leveled and how much. We have been using the Lynx leveler a for many years. Our oldest set is at least 10 years old, and they have faded in the sun. We got a second set with the first tandem axel trailer, maybe 7 years ago. All are still useable. I want to be able to adjust in1" increments so we never liked the wood blodcks. We do use a set of 8 wooden blocks screwed together for the tongue since the trailer sits pretty high.
