SELF-CONTAINED VS. UTILITY HOOKUP
Travel trailers and fifth wheels are designed to be self-sufficient in remote campsites. Carefully watch
water reserves, propane gas, battery power, holding tank capacity (and more important, tow vehicle battery
power and gasoline).
The following chart shows the source of power or supply for various trailer components depending on
whether you are setup for self-contained operation or at a RV park hookup.
