"Take-apart-able" portable generator box -- suggestions?

We have the Supergenproducts tent for our honda 3000 and use it when the generator is out of the truck. Main reason is not to advertise what generator we have sitting around the campsite. It does lower the sound but we usually camp with a couple who have two no name "honda" generators that when running in parallel sound like a plane taking off. You cannot hear our generator when their's is running...
