I would definitely disconnect the unit from the septic. The traps can dry out over the winter and allow sewer gas to enter unit. Empty water heater ( remove anode rod (suburban) or open drain plug (Atwood). Remove inside and outside shower head and sink sprayer if equipped. Put antifreeze in all drain traps. Once drained, leave black and gray tank drain valves open just a crack so water does not accumulate in PVC plumbing, but critters can not enter. If you cover ( I do) use a good RV cover that breathes and secure it good so it does not blow around too much. Will it be plugged in? If so you will need to check battery water periodically. If not, I would bring battery home. Remove anything that can freeze ( cleaners, etc)
