I'm looking to install a water tank in our trailer.. We are currently carrying water in 3, 7 gallon blue containers.. So 24 gallons of storage would be about right. The trailer is 46" wide, and I plan on installing the new tank in the front of the trailer, raised up a couple inches off the floor, and running a spigot out through the sidewall.. There are many different brands on the market.. How does one choose a water tank meant for an RV for use in an off road excursion trailer? Any thoughts would be appreciated !! Thanks
