I dry camp about 30+ days a year. Watching tv with satellite a few hours a day will make even a large battery bank draw down after a few days requiring daily generator run time to keep the batteries up. I have also converted most of my lights to LED. Solar panels are the way to keep the batteries up so les gen run time is needed.. Solar panels are in my future my only problem when dry camping I like to park in the shade as temps can get in the upper 90's. don't know how much help the solar will be in my case...Large portable panels would be a pain to move arouund. Now that solar systems in the 300w + have come down it maybe worth the effort...
