Idea for running TV's off inverter

I just purchased a new 2013 351 DS Georgetown. I think it would be convenient for my kids to be able to watch the TV's while we are traveling. I want to run my idea by everyone to get some input.

I want to run an extension cord from the current inverter to the compartment under the bed behind the fuse box. I will connect that to a new auto switch exactly like the one that is currently installed to switch the refrigerator from battery to shore. I will then wire that into the fuse labeled rec. This should power all of the entertainment devices.

My concerns are:

Will the current 1000 watt inverter handle a couple TV's in addition to the refrigerator?

If I opt to install a second alternator, do I need to get a sine wave inverter?

Does anyone have any feedback for me on this?

I think that the batteries should handle it while driving because they are being charged off the alternator.

DW and I have different opinions on this sort of subject. I don't feel comfortable letting the kids roam around free in the cabin in case of an accident. I like them strapped in the seats. She then reminded me of how I grew up riding on the back of my dad's pickup. She also reminds me that part of the reason we went from a TT to a Class A is so that the kids could travel comfortably. To me, it just doesn't make sense that the two adults up front wear a seatbelts, but the kids outback don't. On our trip to FL I would fire up the gen to let our older one go into his bunkbed and watch a movie for a while. The way I figure is that when we used to make that 1k mile trip on our truck w/TT they would be in kiddie seats the entire time...at least on the coach they can take breaks and get up, go to loo, etc.

We got our oldest one an Ipad to keep him busy this coming up season and I'm going to run an extension from the inverter to either the kitchen or dining area. He can keep his Ipad charged and one of those portable DVD players should be good enough.

Your idea sounds good...a little complicated, but could be done. I'm sure there are different thoughts about the seatbelts. DW and I will still be talking about it next season.

Could probably handle a new style tv or maybe 2.

Probably been more miles traveled before seat belts than since, BUT, you make a very good point. Strap them in! I do believe there are rules governing unbelted passengers.

Your idea sounds like what I would like to do in my coach
You would be pushing the watts for all devises running at the same time on the same inverter of the refridge.
I added up my TV, and dvd/dvr/stereo. They totaled about 310 watts. The fridge takes about 600 watts
If you can use your first idea with a new inverter and a transfer switch installed near the batteries and run wires to the breaker panel that would be a very good idea. That is the way I plan on doing it in the spring.
Watch a recorded show or a DVD is a neat idea for long and boring drives at time. Also when you stop for a short rest.
Good luck and let's us know what you did and how it works.

Wrapperman-

Are you confident about the 600 watts for the refrigerator? It seems like the 1000 watt inverter should work for the bunk TV's. if that is true.
Does anyone know why they used a sine wave inverter? It seems like sine wave inverters are for TV's.

I just did some research and the frig is 120 volts 8.5 amps. That should be 1020 watts. If this is the case then the inverter is beyond max already. Why would they put an under power inverter in the coach.

Well it looks like I definitely will need an additional inverter in order to power any other 120v items.

I just vaguely remember reading online about how many amps the refridge used.
It's been 6 months since I read that. 8 amps seems to be an awful lot of amps for a refridge. I thought it was about 4 amps. If I find it different I'll post it
I'll do some research cause I would like to know myself.
A pure sine wave inverter can power a fridge or electronics.
A modified sine wave can also power a fridge but it sometimes makes a louder hum and as for electronics most TV'S and stereos work fine but it might produce small amounts of white noise on the screen. Cell phone and tablets sometimes have a harder time using modified sine wave inverters
I'm any case you need another inverter
I am trying to find a xantrex inverter with a built in transfer switch. Between 600 to 1000 watts. And installing it in the bay door next to the batteries and running romex wires to the breaker panel and splice it between the breaker and line going to the rec load.
You should try to instal the inverter as close as you can to the batteries. But keep it in a dry place.
Doesn't sound like it would be too hard to rig up.
Good luck and let me know how you did it.

I should have looked at my refridge
You were right. It shows 8.5 amps @ 120 volts
This weekend I will look on the inverter and let you know how many watts it is just so you and I will know.

Just run the genny. It provides many other conveniences beyond the TVs.. with my 3 kids, pretty much if the wheels are moving, the genny is running. At a half gallon an hour, u won't even notice it on the gas gauge.

Hmm let's see networx

1/2 gallon per hour huh. That's about $1.60 per hour.
New 1000 watt inverter $250.00

That's 156 hours of fuel.
That makes way too much sense.
