I don’t personally like it, but it’s done all the time.

This may apply to motorhomes and E Series (with the hump) but cutting the frame behind the cab on straight frame is rarely done. You have to double the frame and resell is non-existent. Majority of commercial mods involve adding frame to the rear, unbolt and slide axle(s) back, drill and re-bolt, extend drive shaft. Any "hump" frame nearly has to be cut behind the cab. The Axis and Vega most likely are done in the manner I mentioned...not cut behind the cab. All straight frame chassis' are done at the rear.
