So the heater is a heater for people? Ok. Was thinking it was for the engine or something lol. Interesting. Your fam uses it in the summer??

Yes, for people. You could add it later, but why? Just get it from the factory.

Yep, they use it in the evening on the way back to the dock. They're girls, they're always cold.
