Wheeleze cart or buy their tire axel combination and build your own. YES expensive but you will only have to do it once. You will end up saving money over the LONG HAUL. If you come to Baja you will know you did the right thing.
MUCH easier than something with wheels that do not work in the sand and rocks.
Do it right once, no more problems. They are great and hold their value. Hard to find used.
