Well I just looked at ordering the fulton kit and when I measured my tongue for height and width it's 3" wide and 2 3/4" tall. Not a true 3x3. I called etrailers who referred me to fulton about the 1/4" difference and was advised not to use the 3x3 and they didn't have one to fit it. My seaark came with a diamond city trailer and I calle diamond city and they gave me their supplier, rockwell american. I called rockwell american and it was the same story...3x3 or 3x2. I dont want to put a 3x3 on it because Im afraid I weaken the tongue even with a spacer. Isn't there a dealer on the board over in west memphis that deals with Seaark? Wonder if they have any insight as how to approach this. Also wonder if Seaark is still using diamond city and if the tongue dimensions are 3x3 now?
