Battery Cutoff Switch
If you RV didnt come with one installed i would suggest installing a battery cutoff switch. When your RV is parked you can physically disconnect the battery from the RV making sure nothing can drain your battery
Solar Cells
Inverter
If you are running from your batteries often or use solar system and require 110V for certain equipment you can use an Inverter. The Inverter creates 110V from 12V.
Keep in mind the batteries are limited and using an inverter may quickly deplete your batteries. If you can try to use equipment that does not require an inverter
Generator
boon docking often? A generator may come in handy sometimes. You do not want one of the cheaper contractor type generators. They are very loud.
You want a so-called inverter generator. These types of generators used to be very expensive and limited to either Honda or Yamaha but in recent years several other brands have come to the market and delivered good inverter type generators for lower prices
Firs you want to decide on what you want top run from your generator. if you want to run your AC unit you pretty much need at least a 3000W generator or more.
Honda has a 2000W as well as a 3000W and larger untits. You can also parallel two of the 2000W units as well
Champion has some great units now at more affordable prices and Harbor Freights Predator line seems to get pretty decent reviews as well
Fuses and Breakers
RVs have a 12V system as well as a 110V system. The 12V system generally uses standard automotive blade style fuses and the 110V system uses standard household breakers.
You can find a fuse/breaker panel in your RVs converter
