I recently (last week) took delivery of a 22' with 2' dove tail, 14k flatbed GN from Kaufman of TX. I am very happy with my decision to go with them and with the trailers fit/finish so far. He (Andy from Kaufman) told me it would be 4-6 weeks for delivery (it was a custom build). I got it in 4-1/2 weeks I think it was. I think it has allot of nice features and seems well built.
I originally was going to go with a Big Tex trailer from a local dealer but it would have been several thousand more and would have also been a 4-6 week delivery time. I think Big Tex makes a fine trailer but IMO their prices have gotten way outta line. I would buy another one from Kaufman. I may look into a dump someday and they make a darn nice dump too. They had a 16' dump the delivery guy was towing behind my GN and I got a chance to look it over, very nice and reasonably priced as far as dump trailers go.
Here's what I got and the total delivered ($600 for a GN) to California if it helps you.
-Gooseneck hitch (adjustable 30k rated)
-20' flat deck with 2' dove tail (22' total)
-Fold down ramps (adjustable and spring loaded)
-Front tool/chain box (LOTS of room to fit tools and chains)
-Dual 10k drop legs (spring loaded)
-Spare tire/wheel
-Stake pockets instead of pipe rails on the sides
-Dual 7k axles (they are dexter easy lubes with 16" wheels and 10 ply tires)
-Brakes on both axles (tell them if you want a 7 pin trailer plug, they come standard with 6 pin)
-I think I hit the major points..........$4380
Let me know if you need/want any more info, Hutch
