Took my RTIC 45 camping a couple weeks ago as well as took it out on my boat for a hot afternoon. It performed like a champ. I did not pre-cool it and it was sitting out in direct sunlight for hours and hours. Hardly a dent was made in the ice. I'm thinking this is gonna be my new buddy for camping and truck. I just ordered RTIC 20 for the boat and other smaller/short trips. I like sturdy and rugged build of these units.
