I knew some traveling salesmen from my previous occupation. I’d say they’re about 50/50 on character. And, believe me, I’ve been fooled by a lot of ‘em.
They do eventually over time spill their beans. Most all of them live out of the car trunk, making the trunk just an overgrown purse for these fellas — it is their life’s sum total of being (clothing, products, self entertainment, refreshments... etc).
