This will be my first large project, certainly my first large woodworking project. I refinish and modify electric guitars so at least I am fearless using tools around expensive parts

My plan for this trailer is very simple, and revolves around unhindered practicality. My goal is to have a mobile bed/ dry cubby for when the fly-fishing is so good I need to live on the river or when the snow is so deep I can't make it home from the mountain. The trailer only needs to be 4x8, big enough for me and a lady if she dare intrude. Other than that I want a single indoor burner in addition to a very simple shelf for the outdoor burners/ grill, and a decent sound system.

As you can see I left the design very open, I have no need for intricacy, I want a clean interior with visible, accessible storage.
My Harbor Freight 4x8 trailer arrives tomorrow and I intend to built it on Thursday, once that is complete I need to clean the workshop with my roommate (its his father's). I am hoping to finish this on Saturday and set up an area to work on Sunday. Currently I am unemployed and just taking a few classes for fun so I am hoping to complete this project inside of 2 months (I secretly think it might be sooner).
I will keep this thread updated with pictures once I start building, I expect to finish the floor next week, hopefully cutting the walls by the weekend!
I'll leave you with my costs thus far:
HF 4x8 Trailer - $400
Speakers (retrofit in-wall system) - $50
Windows - $130
