A second bit of info, if you are not familiar with RV, is a hint on how we may have to search for info.
Like our house, the RV is made of several groups of parts and those part are often made by different people who have their own manuals!
So we look for things that are made by the RV builder but often other things like frig, stove and furnace are bought by the rV builder and we need to find brand, make and model of the specific item we want to know about if we want really good specific info.
The RV manual if you can get one, will be somewhat generic and good for finding some things like drains, etc. But for the best info on things like how to work the furnace and certainly how to repair it, we need to go to the manual from the furnace builder!
Kind of like at home? If we want to know about the front door, the builder may know, but if we want to know much about the frig or furnace, we need to ask the folks who build it as the home builder may only know how to open the door on it!
Point on the electrical? There are two sets of wiring in trailers.
One is the regular 110 AC that we have in a house and powers things like microwave, Air conditioner, and the electrical outlets.
This 110 power also powers some form of converter which changes the AC power to 12volt Dc power. A box that hums when you are plugged in?
This DC power then runs most of the smaller things like vent fans, lights and controls for things like the frig and furnace. Any excess 12 volts not used right away is stored in batteries and used when you are not plugged in.
Got a switch , often somewhere near the entry door for battery cutoff when we store the RV?
If the lights don't work, try changing that switch as a tricky one to know about when first looking at the new toys!
We've all been there and still have to do the same search every time we switch RV, so just go with the flow until you get better info?
Best of luck on the new game!
