TT Electric battery maintenance
OK I am wondering about this and maybe some of you can help. I have a adapter that goes onto my electric plug that converts 115volt 3 prong plug into my TT plug. My question is, will this allow me to...

I have two trailers parked at home plugged into 120VAC separate 20AMP Receptacles in my garage. Separate meaning each 120VAC 20AMP receptacle is on its own circuit breaker in the garage.
I use a Heavy Duty 50 foot contractor grade 10-3 Extension cord from the two receptacles out to the back yard where my two trailers are parked. Then I use a RV 30A-15A "Long Dogbone type" adapter that allows my trailer 30A shore power cable to plug into the extension cords. I make sure this 30A adapter does not ever get hot by feeling of it when initially installed. Be sure to use the large 10-guage 10-3 Contractor grade extension cords. I have used a 12-guage (12-3) but it starts warming up on me telling me it is not large enough for the loads. I would never use the 14-16 gauge smaller "RED" extension cords like you find in the WALMART Electrical section. They are just TOO SMALL to carry the load. Trying to run your Air Conditioner with this small gauge cable will load down the 120VAC Voltage and may do damage to the air condition as well... It needs to get its proper AC Voltage to operate normally.
Be sure you use this type of RV 30A-15A long adapter available from WALMART
You can not use these small round small adapter as they will get hot on you and eventually burn the contacts of your 30A Shore Power cable and require you to replace them.
This setup allows me to use just about anything in my two RV Trailers including the air conditioner however with the 20AMP Service I am only able to use the high Wattage items only one at a time. i.e. I cannot have the Air Conditioner running and then try to use the microwave as this will trip my 20AMP breaker in the garage.
I use this to keep my batteries chargered all the time using the on-board converter/charger unit. There is a caution here however especially if you are using a single mode converter/charger unit. If you leave 13.6VDC on your batteries for a long period of time this will cause the batteries to boil out their fluids which will destroy your batteries. You have to watch your fluids every week to make sure this does not happen. when the fluid level gets below the cores in the batteries they will short out on you with the deposits build-up. Always keep the fluid level above the cores.
I also use one of these RV 120VAC PLUG in meters in each trailer where I can keep a good watch on the AC VOLTAGE level before turning on any high wattage item. This plug-in meter has a the SAFE ZONE marked in GREEN and if the AC VOLTAGE is not within this scale reading I do not turn on the high wattage items (like the Air Conditioner)...
Been doing this for years here when parked in my back-yard setup ...
