Here is some basic info.....
Trailer has 2 electrical systems
120VAC for A/C Unit, microwave and 45A Converter that can supply the 12VDC System when connected to AC Power source plus maintain/charge battery
120VAC Panel with 30A Main Circuit Breaker and Individual Circuit Breakers
12VDC System for tongue jack, lights, fridge/water heater/furnace controls and functions, water pump, etc
DC Fuse Dist. Panel with Fuses for the Individual DC Circuits....part of the AC Main Power Panel
Two 30# (7 gal/each) propane cylinders on tongue with Pigtail hoses to an Auto Changeover Regulator to controls the RV LP System Pressure and Flow
Propane supplies gas for stove top/oven, fridge, water heater and furnace
*Water heater/fridge/furnace have electronic ignition of gas
****Valve in one Propane Cylinder ----OPEN the valve SLOWLY/turn lever on Regulator towards that cylinder/then valve in the other cylinder SLOWLY
***Light stove top burners one at time on high to get propane flowing (water heater/fridge/furnace may need several attempts before propane flow is established at each one)
Probably gravity fill port for fresh water tank...pump can supply RV Plumbing System
City Water Hose connection to also supply RV Plumbing System when available (should use a water pressure regulator set for 50 PSI and an In-Line Filter on potable water hose to RV City Water connection)
Black tank....toilet gravity dump into black tank
Grey tank....Kitchen/Bath sinks and shower drain to grey tank
Waste tank dump valves...connect sewer hose to outlet...open grey first to check connections then close it--open black and dump it/close then open grey to dump it and 'rinse' dump line/swere hose with siapy grey waste water.
*Dump Waste tanks when Full (at least 3/4 full). High level/volume of water moves stuff out of the tanks.
Black tank---use adequate water (high liquid to solids ratio) so you do not end up with a Poop Pyramid
