Newbie to trailer building but not building! :)

Good afternoon, yall! I am looking for design ideas on how to add a wall, door and window to the rear of my 8'x10' enclosed trailer. I use the trailer for pitting for RC racing up and down the east coast. I have seen alot of different trailers with a door, window and even an AC unit on tracks (for when the fold out door is closed. Anyone have any build plans? Thanks!!!

See the "enhanced by Google" search window in the upper RH corner? That is the key to finding that info for yourself- good luck!
