Hi RKassl,

If your batteries a fully charged, 15 amp service will have no effect on the LevelUps or slide operation. If they aren't, plug in and wait 15 minutes before operating.

IF your batteries are charged, the converter will only have to supply 12vDC power to things like your lights, water pump, and furnace blower. So, the current draw at 120vAC for those items will only total a few AC amps. However, if your batteries need charging, the batteries will initially draw about 5 or more amps AC at 120vAC, add the above loads and you could be about 8 amps AC. After your batteries have been charging for at least 30 minutes, their amp AC draw will be cut in half.

In addition to running your water heater on Propane, you will need to also run your refrigerator on propane if you have an RV frig. If you have a residential type frig, when the compressor runs it will draw 2-4 amps AC.

If you have a tube type or plasma TV instead of a new flat screen LED TV, it will draw 2-3 amps AC as well.

So far, with all the above you're doing ok staying below your 15 amp AC limit. Where you will have problems is when you start using almost anything that produces heat: coffee pot, microwave, heater, hair dryer, etc. Each of these items will pretty much eat up your 15 amp AC capacity by themselves. The other big power hog is your air conditioner, it uses almost as much as the microwave. If you want to use any of these devices, make sure your batteries are charged and the water pump and furnace blower are not running.

So to sum it up, if your batteries are charged you will be ok running most things like lights, TV, frig, etc. But, if you want/need to run something that gets hot (or air conditioner) pretty much every thing else needs to be off.

Make sure to use your regular trailer power cord and have the 15amp adapter right at the outlet where you connect, don't use a home type extension cord.

I hope this give you some info to help you manage your limited power availability. If you end up tripping a breaker, just turn something off, reset the breaker, and you're back in business. If you do loose power it will most likely be that you tripped the 15 amp breaker supplying the outlet the rig is plugged into.
