Not sure what vehicle insurance costs in Indiana, but that is what put a dent in my calculation of keeping a fuel efficient vehicle.
The 2500 Burb will work, and fuel economy will be much better if it is a 2008 or newer with the 6spd transmission.
If on a budget, I recommend a 3500 Chevy Express. They are much cheaper than a Burb, can tow same and take heavier hitch weight, and have many seats and seat belts. It will not be as nice as the others, but there is something to having older technology and less electronics. I have installed Bilsteins on mine, and that has improved the ride.
