Hey guys. So Im currently working on a hot water system for my truck. After taking my truck to Tahoe for CRUISER GOLD RUSH, I had a really cool idea for a hot water system.
I need a new radiator, so Im getting one custom made by Champion.
Its all aluminum with an attached oil cooler that i dont need for my transmission.
So heres the plan-
I get a 12 gallon tough plastic food-grade water tank designed for RV's or boats. The tank fits up under the body between the rear driveshaft, and spare tire, just infront of the rear axle to allow for flex etc.
I run a filling line up into the rear bumper, then a "high pressure" line from the tank, to a 12volt pump, to the oil cooler. Then an out line from the oil cooler back to the tank. This is the closed loop.
Then I put a T valve in front of the pump, and run a line to the rear bumper with a quick disconnect coupling.
So when Im driving to camp or to go surfing etc. I flip on the pump from the cab and let the water recirculate for a while so it heats up.
Then I get to camp or whatever, switch the valve, and BOOM. pressure-fed warm/hot water! and food grade too.... so I can cook, shower, do dishes or whatever with it!
Ill post many pictures.
