Jeff, if you are going to be rude, I'll have to step in with my
.
Barrman is NOT speculating, he is stating facts. He did not say you would die, he said you will get a headache. This is from carbon monoxide poisoning from the exhaust fumes.
I have driven Blazers and similar vehicles since the mid-70s. My first was a 1971 Blazer.
Every single hardtop I have driven with the rear window open has sucked in exhaust fumes, along with road heat. If you drive with the rear open, the air blows OUT the front windows, confirming that the air is coming in the back.
Driving another SS members M1009 that had no rear window when purchased, at highway speeds, I have had my drink cup blown out of my hand and OUT the driver's window.
SOFT TOPS tend not to as badly, since there is so much air flowing in from all sides.
No top, no problem.
Having a difference of opinion is fine, but let's do it without name-calling.
Cheers
