With the crazy fuel prices and getting the power station a couple weeks ago it immediately lowered my idle time, looking at fuel gauge and having more fuel than expected. Most of the times idle is not just for comfort but more about powering things we need when not driving. The Predator 2000 Watt Power Station is running all the things I use after a days driving, microwave, laptop, tv, charging devices, all of those things at once too with plenty of power left over. I charge the station each morning as I drive taking only one hour, everyday I am loving this thing. My truck has idled maybe a little over an hour total in a week, those were times when sitting in lines checking in, pre trip startup, and small things like that. Best thing I have had in a truck in years.
