Do all restroom trailers need a fresh water hookup?
I'm looking at renting a restroom trailer for a weekend wedding at a ranch outside Austin. We'll have about 150 guests over two days, with catering and an open bar. The site has level ground and good truck access for delivery, but there's no water spigot anywhere near where we'd place the trailer. I know some trailers have onboard fresh water tanks, but I'm not sure if that's standard or an extra. Do all restroom trailers need a fresh water hookup, or can they operate independently with a tank? If they can, how often would a tank need refilling for a group that size?
