Im not much of an advocate for single purpose GPS's these days...especially
when you consider what a "smart phone" can to with the WAZE app (real time re-routing & alerting based on data provided by other users).

but this Dezl unit from Garmin had some pretty cool "trucker" type features (including custom input of vehicle dimensions and truck specific POI's)

they even have an option to add a wireless (backup?) camera
