Roadside service from
Coach Net, Good Sam, etc. I recommend
Coach Net as they seem to not leave you stranded on the side of the road for very long.
In addition:
Good quality surge suppressor such as a Progressive Industries EMS-PT30.
Good sewer dump hose and fittings.
Fresh water hose
Water pressure regulator
There are numerous other items to consider but this should get you started.
