The PJ 7712 is the exact one I'm close to buying. The dealer was closed today when I went to look so I had plenty of time to check them over good. I'm very impressed with the welds (at least on the one I saw). I agree that the lay flat gate is nice. I also like that the sides can be removed so it can double as a flat bed trailer if I have something over-sized to haul. They also put more marker lights on the trailer than other brands I've looked at.
I'm going to the trailer dealer tomorrow afternoon and will try to talk them into throwing in a dolly jack so I can push it around in the garage. Either way, I think this is the one I'm buying.
They are $1,525 around here. Is that close to the price that you are seeing?
