Especially if you precool your drinks in your home refrigerator. Having a cooler drained battery is not good. Spoiled food, nothing else will run and worst of all warm beer. The ice company's kids need shoes too.
That's the conclusion we came to after camping this week. We used $4 in ice for almost 3 days and even having the cooler sit outside overnight the ice still wasn't melted and everything was nice and cold.

OP was only running lights and a TV. No fridge or cooler.

Speaking of coolers... does anyone use dry ice?

anything's possible...

I cruised for several years on an 18 foot sailboat....these trips consisted of three nights, four day outings.....

night before launch do a grocery shop...put all the meat in a bag and ask the clerk to put it in their freezer overnight...pick up in morning (common request around sailing/marina areas)....

one block of ice, frozen meat....that smallish cooler was one large block of ice starting AGM battery ran the boom box, tiller pilot and a cabin light for the four days with no problem....

great trips...."the smaller the boat, the more it gets used...the more interesting places it gets to"....

if my big fridge ever quits I might just build a real good ice box, in it's place, in my trailer...
