Experience towing w/ 2WD F250, 2500 or other 3/4 ton

I have a 2wd Duramax. I pull a lightweight 5th wheel toy hauler. I also pulled it with a Chevy 1500HD. The diesel is much quieter and gets much better mileage. I've gotten stuck in the Duramax twice, never in the gas truck. Yes, even wet grass. Doesn't take much of a tow with a 4wd buddy. For example I was stuck at an Indy Speedway campsite on wet grass. The Tow truck couldn't budge me. Some guy in a 20 years old F150 4WD got me right out, no problem.
