Reading this thread makes me feel guilty about what my CS 20 sits on. About 14 years ago I bought a used 1987 trailer that had an 18' inboard outboard sitting on it for $250. . The 14" tires were new. It is galvanized and looks like it has lived in many places. The boat rests on 7' 4" 2x4 bunks with carpet and some keel rollers. The back of the boat hangs over the back of the bunks by about 3 1/2 ft. 4 years ago I bought new tires and had the bearings packed. I squirt grease into the bearing buddies occasionally. I live in the Denver area. The trailer and boat have been to Lake Superior, Anacortes, WA (boat to Friday Harbor), the Texas 200 3 times. I have not had a flat tire or an trailer problem. I should have taken a leaf out of the trailer but I did not so it is a stiff ride for the boat. Pore thing.
So I m probably due some bad luck this year when I drag the boat to Port Isabel for the Texas 200 again. It is about 2500 miles round trip. Gotta buy a cartridge for the grease gun and check the tire pressure.
