1980s & Beyond: In-cab tanks largely disappeared from mainstream pickups, replaced by frame-mounted or rear-mounted tanks for better crash protection.
Why the Change?
Safety: The primary reason was to reduce fire risk in collisions; in-cab tanks (or those just outside the frame) posed a severe threat.
Regulations: Federal safety standards pushed manufacturers to relocate fuel tanks to safer areas, often within the frame or behind the axle.
Those durn Fed safety standards. Safest place inside frame behind the axle. Believe what you want.
