I replaced the fridge/freezer unit in my boat
with 2 of the Engel drop in fridge/freezers. The insulation
on the original was shot so I tore out everything and installed the Engels.
They have been doing stellar duty for 3 years now, and we are in the tropics. Very happy with units, even more important, wife is very happy with units.
The inside is completely smooth, easy to clean and they draw very little power, somewhere in the vicinity of 2.5 amps(12v) each. Solar panels
keep them running no problem.
