Battery dead, connection issues

Well, I have the beautiful new Winnebago on the property now, and won't be getting the 50 amp power post for a few weeks. The battery is completely dead, so that not even the carbon monoxide light is on. I went to youtube and to this forum to read up on recharging the battery/using power from the house, which is about 50 feet away. This is what I did, and it did not work:
1.) bought 2 dogbone style power adapters - 50-30 and 30-15.
2.) plugged in the 50 amp cord that came with the rv, then connected the adapters and plugged into a heavy duty extension cord, then into house outlet.
3.) Made sure extension cord and house outlet are working (I plugged the RV television into the extension cord and it has power)
4.) Made sure the battery disconnect stayed on (battery is connected)and turned off all battery operated and electric switches.
5.) Let it sit for several hours - still totally dead
6.) Went to hardware store and replaced the 30-15 adapter just in case. I have not replaced the 50-30 one yet, but they both look to be in perfect, new condition.
7.) Plugged everything up again and let it sit for several hours.

I called the RV dealership and they think it should work. Only suggestions were to suspect the adapters and make sure the battery disconnect is on.

I understand that the long extension cord can cause the power to trickle, but it had juice for the television in the rv. Seems like it should have at least delivered some power to the battery or be operating some of the lights. Everything is still completely dead.

I may have to get an electrician out but first, thought I would ask my trusty, experienced fellow RV'rs out there. Thanks in advance for troubleshooting advice!
