My Dad gave me a heavy galvanized boat trailer with 15 inch wheels. It was used to haul a 19 foot glass ski boat. As you know, the crossbeams are "V" shaped to accomodate the boat's hull. I'd like to cut the crossbeams out and replace them to gain ground clearance and convert to utility trailer. Is galvanized C channel available for the crossbeams and what rod should be used for arc welding? Is this a worthwhile project are just another "money pit" ?
