The tanks on the Greyhawks are not insulated. The combination of a high ambient temp, extremely hot asphalt, and the hot exhaust running under the coach, all add up to some very hot tank contents. And I mean ALL the tanks.
Two years ago, we drove to Glacier NP. 114 degrees at midnight in Vegas. Roof A/C quit working. Dash A/C provided no relief. I felt like I was going to have panic attack. There was nothing cool to be found. Tank water was blistering, temp inside the coach was blistering, temp outside was suffocating, and there was absolutely zero breeze. To top it off, these fridges struggle to cool at all at those temps. Everything frozen melted. Getting ready to drive through Vegas Friday. Temps are to be a few degrees cooler. Hope the A/C works.
