Yes I build the trailer prior to the boat, went to boat shows with tape m. and angle finder worked out only changes is side guides. Next will be a modification when loading on steep ramps, the bow rollers sit too high and give me problems, the 5th wheel plate latching is great towing on all roads better than a pull trailer, have been to Prince Rupert an back no problems, wheel bearing seals get the double lip kind. My deck is 30 ft. long so you could get by with 32ft. rails P/S go with elect. activated hyd. breaks -- Disk. My next project.
