machine room in a trailer?

The US Army has at least one caravan of 8 or 10 rigs that's labeled as war-games simulators. Who knows WTH it really is. ;) Looks to me like you'd be far better off building on a transport frame than a mobile home frame. A semi flatbed or van will be designed to hold up under heavy loads and unevenly distributed weight. Also, it's been my observation that most "mobile" homes are designed and built to move once or twice, and start breaking up after that. For power and cooling, you'll have to give some thought to the expected target environment. If you'll be running it in, say, municipal auditoriums or arenas, assuming high-voltage 3-phase input might be reasonable. If you want to be able to fire it up just anywhere, a light-plant trailer makes better sense. Doc
