I think for you it would work great Chris. You use it mostly local and once in awhile the Hemi will tow an enclosed trailer over the mountains when you need it. If you were enclosed towing over the mountains all the time the Diesel would be the choice.
If I didn't own my truck already I would be buying a Henway not a diesel. If your truck is a six speed my kid is looking for one BTW.
