I have been in the market for a heavy duty tandem dual gooseneck. I found a 32' PJ with tandem dual 15k axles with electric over hydraulic brakes. It had a five foot dovetail with monster ramps. It was a 2016 model bought new less than a year ago. I gave 12.5k for it. When I got it home I was going through the tool box and found the original invoice. The guy paid 23k for it in September of last year. These types of trailers were bringing a premium when the oilfield was booming but can be practically stole right now.
