Wave 3 Heater - old version vs. new version

Does anyone have any experience with the current version of the Camco Olympic Wave 3 Heater compared to the previous version? Both are currently avail for purchase online, new version has been out maybe a year or two. The new version has the Control Knob and starter button on the left and right (opposite edges), the older version has the Control Knob and starter button on the front panel.

I’m wondering if anyone has experience using both versions and has noticed other any other differences between them?


Thanks for your help!
