Well prior to leaving I would fully inspect the trailer to include the wheel bearings, lutes, frame, and boat for any loose items. I will ensure the motor is properly stowed with the good properly latched. If bearings need alittle grease I'll add it. If ligjts don't work I'll check the wires and bulds for water damage. I'll make any minor repairs needed. If I get a flat while on the road I will have repairs or replace. If the bearing go bad while transporting I will replace the bearings. All repairs would be discussed prior to being completed to inform of courses of actions and price. At no time will I charge more then the cost of parts and a small repair rate. Not sure what the $32.99 is for. But for example to replace a tire would be; tire $70 and labor $10, replace bearings would be; bearings $10 and labor $40.
