Roots in Aviation

This is the best system I've found for my boat. It was easy to install and works great. The can cooler is very insulating and the locking base works as advertised.

I was given a system to try out and it works great for our use. We have it mounted on our tractor and it’s perfect for long days working. Super handy!
