I wanted to know the difference between the Johhny Lightning Powercooler and the Supercooler. I've emailed them several times with no response. They both have the same descriptions except that one is mounted in the bed of the truck, I wanted to know how they and which would be best overall. Thanks in advance for any info on these mystery products!!

 

Just wondering, should you give your business to a company that doesn't answer your emails. What if you ever have problems with it.
