Different situation, different tactic - but the original owners of our all-electric 2010 EggCamper
used it primarily for touring Canada and Alaska, mostly on the move every day, boondocking
most nights. To complicate matters, they both needed their own CPAP machine through the night. They modified it to have three 12V batteries on the tongue with a 1000W inverter located near the bed, and they upgraded to a high amp output alternator on their Hyundai Santa Fe tow vehicle. The three batteries would power their two CPAP machines through the night, and their Santa Fe had no problem re-charging the batteries as they headed on down the road during the day. They told us the also nestled a crock pot down in the sink bowl and had a hot meal for dinner cooking in the camper while traveling, and their electrical
system handled that fine, as well. Not stationary camping, but their modified all-electric setup worked great for them as they wandered the Yukon and beyond....
