Diesel Trucks

I have an 03 Cummins Dodge. 4x4 full box dually. Manual 6 speed trans. I have received rubbings from the Ford and Chevy boys about Diesel and to dual's. "Calling them training wheels" But my race trailer weight over 10,000 lbs with no car inside. Their trucks are not even rated to pull out of my driveway. Would be fun to see how long their ECO blast or what ever you call it. BB chev or Hemi for that matter would last lugging my heavy *** loads around? IT's not even fair comparison. I now see why Ford nad GM cried foul when Dodge introduced the Cummins Heavy Duty. It probably should be rated medium duty. I did have to replace a front hub. I needed bigger tools to even attempt. I have a friend who works at a school bus depot. I saw a 5.9 Cummins a 7.3 Powerstroke and 6.5 Duramax sitting side be side. The Cummins was nearly 200 lbs heavier. Sorry boys. Duramax and Powerstrokes are gas engines converted to diesel. The Cummins? Designed to be a diesel. Now things may have changed in 15 years. But in the beginning? No contest!
