I'm converting our new 6X10 enclosed trailer to a mini-mini toy hauler. I've already built a fold down bed and now am looking for cool air for those hot summer nights where we don't want to take the RV.

I know a 13.5 roof air will be more than enough, but total cost with install and wiring is going to run between $700-800. Going the cheaper route a window unit from one of the box stores I can cut that cost in half. The roof of the trailer will be insulated.

I guess my big question is will a window unit be enough? Or should I just pony up and get the overkill with reserve in the roof air?

Does anyone currently have a window unit in an enclosed trailer and does it cool enough at night to have to sleep under the covers?
