I need a refrigerator for my RV. Details are inside.

I need I cheap refrigerator for my RV that can basically keep sandwich stuff cold enough that I won’t die. Cheap is key.

I have had terrible luck on the Internet finding my ideal “dorm room” fridge.

Cheap and won’t kill me… That would be ideal. I’m looking to spend under 100$ if that is doable. I don’t drive so I am cool with paying for shipping.
