Sports chassis and similar units becoming obsolete?

Couple differences that I see...

That Freightliner will still have a substantial value in 10-15 years, the pickup won't.

That Freightliner has great comfort features like air-ride seats, can't get that in a pickup yet.

That Freightliner likely doesn't even "need" trailer brakes, the pickup truck will need some sort of help slowing down at higher weights.

But, for people that like bling, a new pickup truck offers lots of gadgets and gizmos and will haul decent weights with respectable power.
