Bar fridge in storage compartment of a gasser????

I have installed a small dorm fridge/freezer in the front storage of a 5er and it worked extremely well. Obviously AC only so when plugged in the 5er for the night everything cooled/froze and could then travel 8-10 hours a day and still have ice cubes at end of day. Plugged in again overnight and all good. 5er may have more 'vent space' than A but it should still work.
