13: Solar Shower
A built-in shower is something that we’ve covered earlier, but it takes a lot to get a shower into a vehicle. You’d need some type of conversion van to power the shower, and that doesn’t even solve the water problem. But a few smart automotive accessory makers have also come up with a solar shower idea (via The Sun).
This way, you aren’t using the vehicles built-in power to get the shower heated. A solar shower can be used anywhere, as long as you have a water source. This is definitely a great idea for the weary traveler, who might want to stop and take a shower from time to time.
