has anyone ever converted a boat trailer into a flatbed? i have a trailer that had a 16 foot boat on it. its not a roller so im thinking build a deck out of pressure treated wood and bolt it right on. i want to make it around 8 feet wide so it would be wide enough for two snowmobiles side by side. im getting the trailer form my camp in maine tomorrow and i will post pics of the whole project. anyone have any advice or opinions?
