Have always had a gas dryer. Cheaper than electric. I don't know what you mean by 'fumes'. Any gas smell, no matter how slight, is a leak, is dangerous and would have to be repaired.

Ive used Gas dryers since the late 1970s and love them. My wife wouldnt want anything else. As long as they are installed correctly and maintained per manufacturers recommendation, you will get many years of great economical performance. If you use propane you will probably notice some combustion odors but natural gas is very clean burn on all the dryers Ive owned.

Have only had gas dryers since our first in 1987. Definitely cheaper to run and have not had a problem.
Our first was a cheaper whirlpool that lasted nearly 26 years with a couple of minor repairs. Drum rollers were replaced I believe.
Have a SQ gas dryer now and so far has been a blessing to use. Seems to be better built than the WP,more solid feeling, just hope it will last as long.
