A couple weeks back, someone who had had their O'day 192's trailer stolen asked for measurments off of another trailer. I had my boat home for the weekend and spent a few minutes with the tape measure..... Length overall: 18 feet 6 inches Hitch to axle: 13 feet 8 inches HItch to winch post: 29 1/2 inches Height of winch post 26 inches Width of frame: 6 feet Overall width (fender to fender) 8 feet Bunk spacing (center to center) 47 inches Wheel size: B78-13 Tongue extension: 4 feet 6 inches The bunk heights I couldn't get since the trailer is not on level ground and the crossmembers the bunks are attached to are shaped like shallow "V"s and don't provide a plane of reference. I hope this is of some help, Dave
