Main con IMO, and this applies to all pickup Class Cs, as the cab height in relation to the house height. It's not very friendly to passing into the cab, and if you have passengers, they can't see forward. Hardly at all.
At least the OMNI has that upper windshield in the cabover, but it's too high for seated passenger to see the road out of. So... make sure you test drive with any passengers susceptible to motion sickness
