Thanks for any insight.
Your question is wise. The foolish question that we get all too often on this forum is about how to make a trailer 110 volt only.
Usually in 110v conversions someone replaces the fridge with a 110 volt fridge that won't run on propane. This is the most difficult and expensive change to reverse. Prices on fridges vary widely depending on size. You can check prices yourself. Depending on the history of the trailer you may also have to replace the water heater, stove, furnace, propane bottles, and regulator, if these components were discarded as they all too often are. Building up a whole propane system from scratch will cost at least $2,000 and is a prerequisite for running a trailer without 110 volt.
As far as the 12v
system itself, here's materials cost. You'll find that the converter, battery box, batteries, breaker panel, wire, terminals, and ancillary components will run abour $400-$500 or so for a basic system with a 55 amp converter and a single group 27 battery. Lighting and switches don't have to be expensive, but can be if you have taste and get yacht-quality LED lights. Under $100 is possible as is over $500. The remaining components are typically three fans (range hood, bathroom, living room) and a water pump.
The labor to put this all in is considerable. It usually isn't possible to fish wires through the walls, so if the existing wiring is gone, you'll either have to remove panels or run wiring on the surface.
