Yep, we travel at times with 60L waeco in van, I did however wire another socket for this as waeco is a bit sensitive to voltage drop due to light gauge wires.
Ive moved mine into the van instead of the ute because the drain on the Aux battery in the ute with the expanda fridge and the engel drawing from it was too much now the Engel draws from the Van battery and the Expanda fridge from the Ute and all is good. Thought about fitting a DC DC Charger because the Aux battery is in the tray of the ute but it was easier to put the engel in the Van
Hey Paulie
Yup works a treat. My father in law runs like this. He now has a Waeco and finds the Waeco sensitive to the light gauge wire where as the engel was not.
