I'm leaving next week to drive from South Louisiana to Vermont by way of Michigan's Upper Peninsula. We were "loaned" an Igloo Kool Mate 36 that you can plug in to the vehicles power supply. It also has a jack so that once I reach a campsite I can plug it in to a regular outlet. Are there any issues with this? I ran it today while a drove around town just to see if any gremlins popped up. Seemed fine.
Thoughts? Problems?

So I wrapped mine in two layers of bubble foil insulation and it has helped allot. Especially during the day as it doesn't gain heat as easily. That means the daytime high is now no more than 5 to 15 F above the nighttime low.
