Yeah the older dude suggested you could drive for an hour, then take a nap for an hour while charging it, then drive for another hour and repeat... well no, not my cup of tea, not spending all day driving and napping and I often do very long trips, not to mention often being away from civilization when you need to pack the extra fuel with you.
I've also watched some other videos and one of them mentioned the faster you go, the worse it gets. Towing a ~3500# trailer @ 70mph will only give you 70 miles range vs ~100 miles range @ 65mph.
