I have a 2008 Palomino Pony P280. I have used this trailer for a few years now.
I believe it has the Goshen lift system. Now my understanding of this system is that there is a set of springs for front and set for back. By my problem is not front or back but rather the backside or one front and one rear not working. I was able to lift but was having trouble with the door and helper lifting/lowering top to help set door. But now one side is not being held up by tubes.
