Edward, had the Engel 38lt in our 19ss on the passenger side of the engine compartment.Fitted like a glove. The new electronics make the coolers easy to use. They don't give off a lot of heat, just need some ventilation.
I have a larger locally built heavy duty fridge for the 240 that woudn't fit into the 19, It generates more heat, that is 15 years old technology, but works like new & still freezes & cools brilliantly.
