Good question, Robert. There are indeed a few differences between all 3 of the Fogatti tankless water heaters and I have them listed out below:
Fogatti InstaShower 7 Tankless Water Heater - 48,000 Btu # FG37FR
-Lower Btu rating which is better for a smaller camper/RV and or a singular individual
-13” wide, 13” tall, 13-13/16” deep
Fogatti InstaShower 8 Plus RV Tankless Water Heater - 55,000 Btu # FG97FR
-Higher Btu rating which is better for a larger camper/RV and multiple individuals
-13” wide, 13” tall, 13-13/16” deep
Fogatti InstaShower 8 Pro RV Tankless Water Heater With Mixing Tank - 55,000 Btu # FG47FR
-Higher Btu rating which is better for a larger camper/RV and multiple individuals
-Mixing tank that regulates water temperature better than direct flow from heating element
-13” wide, 13” tall, 15-13/16” deep
Basically, the InstaShower 7 would be the base, InstaShower 8 Plus is the middle, and the InstaShower 8 Pro is the high. Hopefully that helps with you decision.

Hi, but they all offer the mixing tank. So as to not have cold starts when washing dishes or lathering up in the shower, yes?
