This Right Here!
We know that the tooling for at least one dirt bike is ready to go. Throw one in the back of the Stepside.
Or, as Luc says, release a Dirt Bike Race Team. I'd prefer a pickup to a Van, but the Dodge, Chevy and Ford Vans, have all been molded in the recent past. I'm not sure about a trailer, but maybe the trailer from the recent '63 Wagon could hold a bike or two. Throw in a sprue full of tool from one of the recent "Top Shop" tool sets, and you have a complete Dio-in-a-Box.
