On-Truck Shower Project..

Seriously, I'd stand up on that cat walk first, there ain't a lot of room
there.
Plus the water will freeze and most fuel islands have gray water in the hydrants.
Put in 51 gallons of fuel a day and have free showers.
Plus if you park by a truck with the tinted sleeper windows, you'll end up on YouTube

 

Never seen one of those as a shower. I've seen plenty as bath tubs. Really hard to get in and out of and the water is always stinky and blue.

 

It's those rotten ohenry bars they always put in there

 

Yeah, they don'the taste very good either.

 

When did they start putting corn in them?

 

Those are bath beads.

 

Work smarter, not harder.

 

Suppose I could help you out here. Before I bought my first big house, I wanted a shower in my truck too so I figured out how to actually make one work. My first un-conventional shower was in an 06 KW W-900 inside a 72 inch sleeper. I bought all supplies from Home depot (or Lowes) and Walmart.
Supplies needed:
1/4 inch PVC pipe and 4 90 degree elbows - no glue unless you want your shower to remain in place all the time
4 small Bungees
1 Heavy Duty shower curtain ( 5.00 bucks)
1 pack of 10 shower curtain rings ( 1.00 to 3.00 at Wally World)
1 Medium plastic tote (used as a catch basin)
1 Black hot water garden hose (that can withstand water temperature to 180 degrees)
1 small 6 gallon electric water heater ($89 to 100.00 at Lowes)
1 or 2 6 gallon green camping water jugs from Wally World
Some hose clamps that fit your water heater inlet and outlet ports and RV water pump ports.
1 RV 12 volt electric water pump that has high pressure cut out ( 89 to 99.00 at av RV store or online)
1 toggle switch
Some decent gauge electrical wire
Butt connectors or solder and electrical tape or shrink tubing.
White teflon tape
Your choice of hand wand- Peerless makes several styles (What I personally have as my shower head in my truck)
Directions:
Assemble the PVC in a rectangle shape, using the 4 elbows, making the curtain holder slightly larger than the circumference of your catch basin so that your curtain comes down at a slight angle-giving you more room to turn around in your new shower.

Attach the PVC curtain holder from the roof - the whole assembly won't weigh more than a pound or so- using your 4 bungees. Hang your curtain using the shower curtain rings.

Place your small electric water heater in your side box or someplace out of the way in your truck, plug it in to your inverter.

Plumb your camping water jugs to the inlet side of the RV water pump, then run another piece from outlet side to the inlet side of your water heater. Another section is used from the outlet side of your water heater to the hand wand.
*** this is where you listen close*** You have the option of running separate hot and cold water lines but they are more work and a waste of time. Your electric water heater has a dial thermostat that controls water temperature. In summertime you can turn off the water heater and the water will merely pass through the tank and come out cool on the other side.
Find a place for your RV water pump and wire it to the switch, switch needs 12 volts of power.
There is a pressure screw on the RV water pump that automatically turns off the flow of water when a preset PSI is reached, this allows you to pause your shower from the hand wand without bursting waterlines from over pressure.
Home depot sells adapters in the plumbing section that will allow you to convert your garden hose to a 3/8 bathroom fitting that you screw your assembled hand wand on.
***************************Test EVERYTHING for leaks before final installation***************************
When you throw the toggle switch, water will be drawn from your camping water jugs into your RV water pump then it will fill your small electric water heater, eventually filling the entire system until you hear your pump cut out (when maximum preset PSI is reached) Wait for your desired water temp to be attained. Get in your shower and make sure your wand is pointing down into your catch basin because the initial bit of water will probably be cold. It doesn't take long for the warm to reach you. The faster you open the hand wand the colder the water will become because the water won't stay in the heater as long. Slowing your water will raise the temp. You'll eventually find your happy place.

Your'e Welcome.
