I bought a used Witzco for half the price of a new Kaufman. I was going to buy the Kaufman 35t detach but the price jumped up $10,000 after F.E.T., pony motor, air ride, wheel wells, inner trailer boards etc. Would I buy Witzco trailers and start a heavy haul business..NO. Nor would I buy one if I had a decent size grading company but for a small fry like me it's fantastic that I can afford one. Those big name trailers are way too expensive. I too mainly want it for stability and safe loading amongst many other reasons. My Witzco does have thin metal all around the rear sections but the beams are big like the other trailers. So yes Witzco is a fine trailer made to hit the bottom dollar mark in the detach market. They have no radius beams, just a straight edge simple design. On a Witzco they may not have the camber or heat treated beams but who cares. That just adds to the price. I'm sure all trailers flex and return. I wouldn't overload a Witzco anyway. The design has not changed in over 20 years so they got it right obviously. All the big companies have to out do the other company in order to get buyers. Kaufman trailers told me those big guys like, Fontaine, Talbert, Entyre, etc. make huge profits and said a few of them were connected. Who knows. They do sell themselves though. Witzco is good.
I take it that 60,000 lb loader is a 973..
