Help me build ideal truck mount set up for carpet & tile cleaning

The last truck mount set up we built by ourselves. We called it the Baddest truckmount set up on the planet! We used the El Diablo fuel fired but this time we are using the heat exchanger version.

Looking back many members had some great ideas I wish I would have implemented. Therefore I am asking for help to build this one in a brand new Nissan NV van.

So if you had a blank truck and a new truck mount how would you set it up ideally. Let your creative imagination run wild and we will see...
