So a month or so back I acquired a Helton Hot water shower system for my jeep through a barter. It is basically a heat transfer device that takes heat from the engine coolant and heats water that you pump through the device.
Yesterday I finally got around to installing it. a few hose clamps, some angle iron, some 1/2 strap, a bit of welding and some hose and it was in and providing some nice hot water from the cold water in my cooler. It will be very nice to have a hot shower on any trip that I go on I am seriously looking forward to taking a hot shower after 3 days in the Uintas hiking to Kings peak in a day or so :)
