I like how your's looks!! I have two questions as I'm about to redo my exit end. What parts did you use to come out of the PVC on the endcap? I have had issues with mine having a slow leak. 2nd Did you put the pressure stem on a removable cap on the filler side? I was going to put mine somewhere on the exit end when I redo it, not sure if it's better to put it on the other end. Thanx in advance. -Jon-I made mine out of 4" PVC. It has a fill/pressurize cap on one end and a hose attachment on the other. Used it this past weekend and it was nice to have a warm shower after riding all day. The whole thing was maybe $50-$60. Everything came from Lowe's. I had to use white PVC because they didn't have black in 4", but covered it in black truck bed liner.
I can take some closeup shots of it if you like so you can see the parts you will need and how it all goes together.
Have you made any decisions? Is it strictly for use as a road-shower style set up or will it serve other purposes? Ex- Shower, Dishes, Hot Water for cooking, coffee, etc.? The reason I ask is because when considering these questions for myself, I got hung up on the quality/durability/cost of the DIY build and the limited functionality of a system only dedicated to showers/rinsing off. I opted for a inexpensive battery operated unit from Amazon that is basically a small battery operated pump connected to a shower head by a length of tubing. It plugs into a 12v battery for power. I can use it for shower, rinsing, washing the dog, washing dishes, etc. It doesn't have high pressure, and I have to heat the water in a pot on a burner and then add cold water to get it to the desired temperature, but it packs down very small and does all I ask of it so far. Under $30. No DIY required... unless that is your goal... lol
