trailer
Vic,You have probably figured out by now that everyones trailer is a bit different. I made mine and used a few measurements from the orginal trailer used by Catalina. That said I made my bunk support hight adjustable. I hope these measurements help you. From the outside edge of the frame the forwards are 16" to center, the middle are set at 11 1/4" to center, and the rear are set at 7 1/4" from the outside edge to center of bolster. Don't be surprized if you have to move them. The trailer I took measurements from allowed the rear of mine to be to far out, I cut them loose and set them in another three inches.
