Electronics help for RC pit trailer....

Okay. I need some help and advice on wiring my "new" pit trailer. I run Friday night dirt oval at Stateline RC in Fremont Indiana and bought an old "pop up" camper, removed the beds and canvas, and now need to set it up. Main question has to do with efficiency. I have used two deep cycle 12v batteries in the past to provide power for my chargers and a small inverter for charging my LED lights. This has worked well and quiet. I have a Protek 40 power supply that I use at home that allows me more current to the charger. Should I buy a bigger inverter to power the power supply and 110v LED tube lights? Seems I'm going from LV to HV back to LV. I really don't want to use a generator, but will if that's the best option. How about longevity of the 12v charge, i.e.: how long will a charge last in hours... Help please.

first .. you may know.. all auto/watercraft Batteries... you NEVER discharge below 50 percent of battery capacity .

best plan.. a 12 volt charger for your RC stuff... the 12 to 120 to 8 or so .. as you stated in NOT Good. do-able but not good..

more batteries... or a generator... just keep in mind.. some generators do not have TRUE "AC" sinewave... but modified square wave.. and will/can make some electronic equipment go NUTS....

as a backup on my Camper.. I have a 400 watt inverter running a 32in flat screen TV AND a satellite box.. just fine.. From a 650 amp hour 12 volt battery.

but will NOT run a stupid electric blanket.. for the wife. blanket will not turn on from inverter.. go figure. but works fine from the wall 120...

and YES.. inverter and generator can & do make modified square wave.... and higher end units make True sinewave..

NO way of telling till you TEST them.
