those who do not have a water heater in the trailer, this is a real
option. Also works well with the 100 gal in my truck. In
emergencies, I can provide hot water from the truck wherever
elect to carry the water on the truck, not the trailer. Most hay racks are
not built for that kind of weight. also I can go and refill the truck any time,
without moving the trailer. Primarily designed as a crew tank, but has a
12 volt demand pump for hosing horses or refilling the trailer tank, and a 1 1/4
ball valve for bucket fill.
I put two standard 35 gal. farm spray tanks on
the top of my old stock trailer. They worked great. Because I am
lazy I used 1 inch farm hose with farm quick disconnects, and ball
valves. I could fill my buckets much faster than at an ordinary garden
hose cock. For maximum ease put one valve at the tank and another at the
end of the hose. Easier when in camp than climbing up to turn on and off
after each bucket.
PS. I also got a hand garden sprinkler head
so I could run the hose into the trailer and use it as a shower. Not bad
on warm days when the sun warmed the water. I never did get around to
blackening the tank to make the water warm faster.
