("Look for a bag of "Linxx" plastic squares or the 2x8 is fine. 90% of the time you only need i borard or Linxx on the low side of your trailer. Measure the 2x8 so that the boards are about 4" longer than the width of the tires. Bevel the ends at 45 deg. angle. Make the second 2x8 3 inches shorter than the first one. Be sure and buy wheel chocks that you can adjust to put pressure on the tires. for each side of the trailer. ")
X2....I also carry several lengths of left over Trex decking planks as help in leveling. I have found that their thickness is just right when only slightly off level.
