Ok, I'm looking at a project trailer for my mostly finisged project boat. The trailer is an older tandem axle with an ancient surge brake system. I have looked it over and the frame and axles look to be in good shape. Outside of that, everything else would be going. New tires, wheels, bunks, brakes (already have these), winch (have), jack (have), keel rolles, guide rollers, psint, and coupler. <br /><br />The only part of this project that is unknown to me is the cost to have the old A-Frame coupler removed and a new coupler (not a brake actuator, the new brakes will be electric) welded in its place. The coupler will cost me about $25. Anyone have any idea what it might cost to get the welding done?<br /><br />Yes, I might be able to buy a trailer that needs less work, but the cost would be comparable, I would have to travel at least 10 hours round trip to get it, and would then have to get it the way I want. I would just assume have the project and build what I need.
