Exterior subpanel with 50-amp receptacle

I am in need of an exterior subpanel with a 240 volt 50-amp receptacle and a 120 volt 20-amp receptacle. Both circuits need to be on their own breaker in this panel. It needs to have the capability to plug in two cords, and still close the cover. This is for a travel trailer.
Any suggestions on brand of panel and part number?
Thanks,
Bryan Klakamp

Midwest Electric Products builds that sort of thing, they're designed for use in RV parks. Go to their website at http://www.midwestelectric.com/ and do a search for part number U055C010, I think it's what you're looking for.
Thanks, Stuart.
I shared this with my supplier, whom I had already requested to look for one for me. He, too, found one at Midwest Electric. He also came up with one from Siemens that will do what I need.
I appreciate your help.
