New trailer - what to put in there first?

I have a new trailer which, over time, I hope to convert into a toy hauler of sorts. It's already insulated with lights and power receptacles, and I have put down the garage floor type paint, so I have the bare necessities covered. Besides that, the trailer as it sits is completely bare. Since this is gonna be a work in process, I wanted to get thoughts on what you would add first to the trailer, based on your previous experiences. For now I will be sleeping in a cot (will eventually add the fold down bed), but really wanting to get thoughts on other things that you have found to be necessities when you camp out of your trailer.
Thanks!

Heat and Air.......I was lucky to find a Dometic Penguin Heat pump AC unit. Works Great!!!!!!!

I would put a front shelf for tools and other things and also some sort of hangers

Frig for the beer. That way you dont have to go far when your working on it.

Upper shelf or cabinet that won't get in the way of parking SxS's. Coat hooks....lol, sound like a broken record don't I.

An awning out side would be nice too.

I was also going to say put in a beer tap we could just ride up to it and poor ourselves a cold beer. That would look good coming out the side that way no beer would get spilled on the floor lol.
