I am looking to stay the night in my car are there spaces here for passenger cars? Are showers for everyone? What is the wait like for the showers at 5am.

There is parking for cars on the gasoline side but try not to stay in front of the store or they might think you're up to no good, better yet ask the store manager if ok to overnight and where to park so no one will bother you. Showers are for everyone but you have to pay $ for it if you don't have a rewards card, if you do have one and put 50 gallons of diesel on your vehicle you can earn a free shower not sure how it works on gasoline cars though but I'll ask for the nest time, waiting times for showers @ 5am is usually not long but at 6 is another story, the earlier the better! hope it works 4 U and happy travels!

Yes! Parking for cars, showers. going quickly.

Showers around 5am have minimum wait time from what I have seen. They allow overnight parking for cars as well.
