That 6.0 would be fine. Yes, diesels get better fuel economy, but the fuel costs more and so does maintenance on a diesel. An oil change on a diesel can easily run more than $100 plus the fuel and water filters can get pricey, too. Unless you tow a lot all the time, a diesel rarely pays for itself.
I looked at the maintenance costs as well when making my choice. An oil & filter change on my 5.3l ran about $50 (depending on if I had a coupon) every 3,000 miles. I usually put about 10k miles on a vehicle per year, so that's roughly $100 per year.
If I have it done at the dealer, (so I'm told) service on the Duramax will run about $150-$175. Add in the DEF which (so I'm told) runs about $35 twice per year.
So on the high side, oil and filter on the Duramax would run about $350 plus $70 for the DEF for a total of around $420...or $320 more per year than the 5.3l I had. Like I said, right now, my fuel costs are about $60 more per month (or $720 per year).
So all told, I'm looking at about $1,000 more per year to operate the diesel...not considering the power and mileage advantage I'll get towing with the diesel.
That's not chump change, but it's not a bank breaker either.
