Yes, that does help. Thanks.Tom's response helps. I guess I'll just add a little.
New question about disk brakes. Does anyone know what to do, if they are slightly engaged when the trailer is not connected to the tow vehicle. (i.e., when you turn the wheel they grind slightly, but the wheel still turns). Is there a trick to keeping them maintained when you don't use the trailer very often? Boat is in a marina slip; just use it to pull boat out for certain maintenance tasks like 100 hour service on engine and installation of gear.
) Put on the two coats of POR15, correctly applied, plus two coats of "topcoat" Rust-oleum. New winch installed (had to order shorter handle (6 inch; came with 8 inch) to clear bow guides), new bow roller installed at bow bunks, new spare tire mount, new rubber handle for the trailer tongue elevation winch. Got tired of getting my hand pinched between the handle and the cap nut. Learned how to get "cap nuts" with decades of rust off---finally! 
Mostly just have left to build new bunks, carpet them, and attach to cross members. I bought a less powerful grease gun so I, hopefully, will deal with my bearing buddies with a less heavy hand and not blow out rear seals as last time. Will need to have my 2013-installed disk brakes checked out by a pro. Not familiar with that gear enough to know what to do. They rub a little when you turn the front tires. That and remount lights and license plate, and I am back in business. I'll wait on the picture until it is all finished, but my hope is to get another ten years of use out of this puppy. I'll be 85 y/o then and most likely ready to pass on my "X" to a younger man and his "admiral".
