Back in 1997 I bought a Dodge V10 for the same reason (Cummins was $5000 more and $5000 will buy a lot of gas). I got tired of the gas mileage and bought a 2001 Dodge 1500 with 5.9 thinking the gas mileage would be a lot better - NOT. Last September I finally bit the bullet and got a new 2500 w/Cummins and really love it. Gas engine - never again. On a positive note for you, I think the 1997 V10 I had towed a bit better than the Cummins I have now. Nonetheless, the Cummins will tow my rig with no problem plus give me 17/22 mpg.
