Not much direct experience for us... we did stop in to see them when we were looking for a used Interstate. Their price was okay but we ultimately found a van with the preferred floorplan from a private seller.
We know at least a half-dozen people who have purchased new trailers form Haydocy. Some of them are repeat buyers. Maybe one of them will reply to your thread. I presume Haydocy wouldn't have repeat buyers if they weren't doing something right.
