I think your original unit you mentioned was 50hz. Not sure if that would be an issue.
Using the 240v model you would need a 12v/240v inverter as a stand alone power supply as I think most truck camper systems are 120v 1ph.
Looking at the specs for your revised unit it's 120v 60hz which is good in the sense that's it's compatible with camper's existing electrical system.
You missed listing the most important specs above.
Cooling draws 8.8a and heating draws 7.2a.
Your going to need a ton of battery's to power those devices yeah?
I would think an electric heater would be my last choice for heating.
Not sure why your getting rid of your rooftop unit unless it doesn't work or ?
Good luck on whichever way you go.
