I talked to a guy who has a honda generator hooked up to his truck & runs a portable air conditioner inside his sleeper. He also has plugs that just run off his battery, which he only uses for microwave & a little lamp. I thought this was funny, but for the price compared to a APU I wonder why this isn't done more often? Do a lot of trucks run similar to this? I am sure messing with the generator everytime you want to start the AC would get old fast, but doesn't seem that bad to me, considering the cost savings. Just want some feedback on this... opinions??
