Cargo Trailer with Slides - Probably Custom

I am in the market for a Cargo trailer with 2 slides. Basically I would like a 30ft bumper pull or even a 5er in the 30ft range. I have not found anything searching the web and suspect that I may need a custom unit.

Ideal specs would be 30ft long and 16 ft wide with the slides out and the ceiling to floor needs to be at least 10ft.

I am looking to build a mobile office.

Does anyone have any thoughts Ideas or suggestions?

With the specs your looking at you may be able to convert a Coach type Car Hauler / race trailer to a mobile office. They have high ceilings with lift floors and some even have slide outs.
Check these out for a starting point they are heavily customizable too.
