I recently put a TV & Blu-ray in my camper but went a different route in powering both units. I purchased a small deep cycle 35 amp battery along with a 200 watt dc/ac inverter. The combined amp draw is about 3-4 amps per hour, so I'm good for about 6-8 movies before having to recharge the battery. I did this so as not to draw from the main battery. Also, I too have to use a CPAP & I have a another seperate 35 amp battery that runs it using the DC power cord that came with it, no inverter neccessary. Once again same reason, no draw from the coach battery. Bought the batteries for $50 each & the 200 watt inverter for $23 on Ebay. If I'm dry camping & need to charge either of the two auxilary batteries I simply start my generator & use a battery charger.
I thought about that too, but it is a heavy, ugly thing to deal with. I tried a large portable jump start battery and it lasted about 1.5 nights even though I left it charging at the ranger station each day. It just never got a full charge during that time. Now I know that a deep cycle would be better and still have the Grp 24 that I replaced with the grp 27. That will be replaced by pairs of 6v golf cart batteries for even longer life. I am going for convenience now as I hope to do more dry camping in the future.
I looked those up and they weigh less than the Grp 24 I have and have those nice handles. They should be good for several days with a CPAP using the 12v cord.
