I have several trailers and have found for me the Great Norther (20'+5' deckover 14K gooseneck), PJ (12' 14k Dump trailer) and Big Tex (14' 7k utility) have all been great trailers with maybe the PJ being the best slightly because of better paint.
With my BigTex the only thing I would change would be a either go 16' or a longer trailer tongue so I could mount a truck box up front, this trailer has been great over the years for hauling everything from quads, firewood, helping people move, barkdust etc... My Big Tex is 14'*7 1/2wide with 2 foot steel sides and the ramp tailgate which has been a great asset over the years.
