Show me your trailer mounted fresh water tanks
 

Looking for ideas. Just bought a fresh water boat Im bringing to salt and want to keep her as nice as possible. Would like a tank on the trailer under the bow to rinse the trailer after launching. Im looking at some complete kits at places like Tractor Supply for spraying insecticide etc.

I was almost set on that idea as well because the harbor I launch out of doesn't have washdown. I prefer finding a carwash nearby, if that's possible it's the move IMO, lot less things to deal with and you can put a lot of quarters in the machine for the price of the setup your thinking about for the trailer and it will be a much better wash down.
Not to steal your post but what is your trailer made out of and what do you put on it? I just built a new aluminum I-beam trailer and I put Rupp Alumaguard on the whole trailer, haven't dunked it in salt water yet after but it seemed to coat the trailer pretty well.

Went to Northern Tool and picked up the Tank. Cut a 1/4 inch plate and mounted it on the tank for vibration purposes. Then mounted the pump on top of that. Ran electric to a On/Off toggle to the Port side in front of tailgate. Stbd side, 75 ft of reinforced nylon hose with garden hose sprayer. Fill hose same side.

Aluminum. Im thinking more for a quick rinse especially the brakes after launching so it snot sitting in all salty in the parking lot all day.

Im thinking of rigging up a sprayer setup on the trailer to rinse the brakes etc with irrigation heads all plumbed just turn on the pump after launching the boat let it rinse until the truck is parked in the lot.

Check out the Evolution Trailers website. They offer it as an option, and there are a couple pics.

that's a good idea, i launch not too far away from home and rinse there, for the axels and brakes i slide a lawn sprinkler in between 2 tires till it's under the keel and let it go back and forth for a little bit
