Does anyone has information on installing a pressurized water system in the F150? Specifically, location and size of the tank and how it affected your vehicle. Ideally, I'm going to be installing a 15-20 gallon system with a UV filtration system in place to filter the water as it's being filled and used. I figure that should give us 4-5 days of water use for cooking, drinking and rinsing off between refills.
