Having never used IdleAire, I did not realize it was that expensive. $1.50 an hour will buy you a 24 hour stay in an RV park ($36), which is an attractive option if your truck is equipped with shore power. Most RV parks provide laundry, showers, water, sewer, cable TV, Wi-Fi and a place to stay that is more safe, quiet and clean than a truck stop.
The down side is RV parks charge by the day, not the hour. For shorter stays, IdleAire and ShurePower are less expensive. Though, at that price, I would run the generator instead of using IdleAire. And since our truck is generator and bathroom equipped, it is unlikely that we would stay at a truck stop at all.
Air-card internet access eliminates the need for Wi-Fi. This night, we are parked on a side street in a small northern California town. I'm online now. Overnight, the auto-start generator kicked in and ran for about an hour to keep the batteries charged up.
IdleAire and ShurePower have their advantages, but there is nothing like the freedom and comfort a full-featured truck provides. Our total "lodging" costs this night are the cost of fuel to run the generator for an hour.
