I puff away when I'm driving. I keep my vehicles until the wheels fall off, average 250,000 miles per car. So, resale value isn't a concern. Your truck will stink like a stale ashtray. Ozium helps, but nothing really keeps the stink away completely. Then there's the matter of cinders landing on your seats and burning through the cloth. You can count on that happening, unless you smoke with the windows closed. And then there's the film that will form over your window glass if you keep the windows closed. Smoking in your car will ultimately trash it. If you tend to keep cars until they disintegrate, as I do, it doesn't matter. Drive with the windows open, puffing away, cinders flying onto the upholstery, a film forming all over the interior, and enjoy.
