I've been using an Eccotemp 5L instant hot water heater mounted on the tongue of my 1977 13-foot
Scamp for over a year now. It works great!
The inspiration was when I went to the vintage trailer
rally at Roslyn, WA last year. There are no shower facilities at the city park where we camp. I had to carry a 5 gallon bucket of water from one end of the field to the middle where my trailer was. I heated the water on the stove for a sponge bath. This year I was better prepared.
I have a 6 gallon Igloo brand tank that is secured to an aluminum hand truck I bought at Office Depot for around $45. It is rated at 250 lbs. It carries 48 lbs. of water across the field easily. I was again in the middle of the field this year.
On the back side of the square steel tubing I bolted to the tongue of the trailer I have a 12 volt Flojet pump that I bought at Camping World. I believe it is Model 3526-144.
The hot water then goes into the city water inlet. Inside I put a tee fitting so water can go up to the sink faucet or straight to a ball valve with a 1/2" NPT pipe on it where I can attach the shower wand.
I stand in a 28-inch diameter plastic pan that is made to go under a hot water heater tank. It is only 2.5-inches deep. I can rinse off without a shower curtain by crouching down and carefully keeping the wand close to my body. I may have a little puddle or
light spray around the pan but most of it stays in the pan.
I've been letting the water run out of the pan onto the grass or into a 12 gallon gray water tote just outside the door. To get the water to drain I have to lift the side of the pan opposite the drain tube to get the water to flow out the door.
After showering two nights last weekend in the trailer I went to a Coastal Farm and Ranch Supply store 2 miles from home and bought a 40 gallon oval plastic tub to replace the hot water heater drain pan. It will work so much better than the shallow pan I've been using.
The 40 gallon tub is 39 inches long by 29 inches wide by 13 inches high. It literally is a bath tub. I definitely won't need a shower curtain with this. I will be able to sit inside it and rinse the upper body. I will then stand up and rinse the lower half.
Tomorrow I will assemble a 1/2-inch pvc pipe which will connect to a 12 volt marine bilge pump so I can pump water out of the bath tub up into the sink where it will flow into the 21 gallon gray water tank under my
Scamp. I bought that gray water tank from
Scamp. It is the one they use.
Because the hot water has to go through a 10-foot hose to the city water inlet, I go through a lot of cold water before it gets hot. I do get steaming hot water eventually. I it really speeds up washing the few dishes I used in preparing a meal.
This winter I will move the mounting for the hot water tank to a hitch-like receiver just ahead of the
refrigerator vents. The 12 volt pump will be mounted inside under the front bench by the
refrigerator with fittings alongside the heater mount. A much shorter hose to the city water inlet should work better.
This is the only time I've had to use the 12 volt water pump. Normally I have water hook ups but not always sewer.
I'm going out this weekend and will try the bigger tub. I will post an update on how that works with photos. I also found the perfect plastic tote at Lowe's for the putting the hot water heater in and all hoses during transport. I do not leave the hot water heater mounted on the trailer when traveling.
It is very comforting to know I can have a refreshing shower anywhere I can get water. I'm looking forward to some day getting water out of a lake or stream if I have to.
