Question about adding an outside refrigerator

[LJS1211]

Have an odd question that I'm hoping someone can help me figure out. Our trailer is a Vibe 250BHS and on the original floor plan there was an outside kitchen option. Our trailer did not come this way so we just use it for storage which is really nice. With that said I'm starting to get really jealous of everyone else's outdoor kitchens and in particular their outside refrigerator.

When we travel we end up taking an ice chest full of adult beverages and drinks for the kids which I store in the back of the truck until we get to the campsite and then put it next to the trailer. I'm trying to figure out if I could just add an outside refrigerator in they spot I'm using for storage.

There is plenty of room but I'm not sure how I would get power to it. I'm assuming I could drill a hole in the bottom of the floor and run power somewhere but don't know where to run it to. Could try and tie into the power for the existing fridge or possibly run something to the fuse box inside. I don't have a lot of experience with electricity or wiring so trying to figure out how to do this without blowing up the trailer.

Any advice or help you guys can give me would be greatly appreciated. Thanks!
