I have a tandem axle flat deck trailer for sale in Creston. It has heavy duty axles and leaf packs. It measures 6' between the fenders and 11' from the headache rack to the back of the deck.
It has a surge brake setup, but the resevoir on the front is empty so I don't know if that works. It's not pretty, but it is tough. It has a large toolbox in the front for storage. It will need a little work on light covers, etc..Email me. I am asking $800 or you can make me an offer, ask for Jeff. (No, the truck on the trailer is not for sale).
