Our rig has the bubble wrap above the coroplast and no tank heaters. We have been at temperatures below 10 degrees and used the furnace to heat the rig and never had an issue with any of the tanks freezing. I’m thinking not much else is really needed. Personally, I think the tank heaters may be a nice new addition but not necessary in the long term. With the heated under belly area, I also don’t see any need for any insulation wrapped around the tanks.
