Hey everyone. I'm looking at building a solar shower for the rooftop of my teardrop that is on order. The trailer has a full roof rack and plenty of room, so I'm thinking of making a square out of 6" PVC that runs just inside the edge of the roof rack and is attached to the rack for security. I would place pads under the shower and angle it slightly toward the rear where I plan to put the outlet. This will allow me to get most of the water out of it while on a trip. I'm fine with the building portion of the project, but I'm not sure how to figure the capacity (and weight) of the shower based on size of pipe, etc. Any help would be appreciated.
Approximate shower dimensions: 60" W x 84" L x 6" Dia
