My trailer started out as a 6 x 10 foot utility trailer bought from Leonard Truck supply. It has a rail about a foot high all around it with a removable tailgate. My rack is simply three 2x4s covered in outdoor carpet and secured with bolts and wing nuts only when I am carrying the boat. The rest of the time its a good 2000# rated trailer. Trailer was about $700, but is built much better than HB or Northern Tools offerings. U.S. built, and price included already installed Hub Buddies (externally greasable hubs, cost about $50 to add later). If you are going to need a trailer for other work, consider a little better one. It is worth it.
