Where in arkansas do you live?
I built my own from a 17cubic foot yard cart adding boat axles and small lawn mower type tires. the thing is invaluable!
I have seen some pretty well built ones around . a place in camden used to build them and i saw some near lake degray.
I like a trailer tailored for atv use instead of a 4x8 type trailer.
i pull mine through the woods and many places that a 4x8 would NOT go!

Let me know where you live i have been considering building some to sell.
