the cummins is a bad choice for daily city driving, they are made to be ran hard, they need to be hammered against the limiter on a regular basis, towing a 10,000 lb trailer at least occasionally, a short commute will kill the pumps and injectors, stop and go they do not like at all.

i have been driving and towing trailers for 20 years, i have had everything from a cummins to a ford and currently have an 05 ram and a chevy 5.3

i love my ram, it will literally pull a house down, it does not even know my 35 foot fifth wheel is behind it, but the advantages to the diesel went away when the price of diesel jumped up past the cost of gas, the gains is mileage are offset by the additional cost of fuel.

the gasser is way cheaper to maintain. I had to do the injectors on my ram this last year. dealer wanted almost $6000 to install new ones, i did them myself, but parts were still $1700 for remans,

I could have done four sets in the gasser for that. tires cost more e loads kill me, i have yet to get more than $30K out of set on the dually,

I drive the chevy 5.3 as my daily driver, $.70 a gallon cheaper fuel and the mileage is better.
