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

I know you did not want a Dometic unit. But for information, I have it installed in the lower compartment. Put in a 120/12 volt power for it. I can leave the compartment door closed it will get warm in the compartment but the Freezer works great. I did add three vents in the compartment wall. When we stop for the winter in TX, I leave the compartment door cracked open. Have been running like this for eight year. No reason why a door unit would not work like this.
