The rest of the credit for the improved driveability belongs to the newly engineered and far stiffer ladder-type frame. Stiffness counts for everything in automotive architecture. It governs how well the wheels stick to the road and it determines how well the body panels fit together. Its importance cannot be over-estimated.
The Mega Cab is immense. Don't even think about using it as the family hauler. You'll have an impossible time at the Wal-Mart. If you manage to get it into a normal-size parking slot, you'll never get it out. However, it makes an ideal mobile office. It's capable enough to handle most roads and non-roads yet comfortable enough to transport the family after work.
While Chrysler claims fuel savings with the HEMI (MDS) of up to 20% as compared with the non-MDS (HEMI), I don't frankly buy that number. I'd get the Cummins diesel. You'll save money on fuel while doing your bit for national fuel security. Besides, you'll more make up the extra upfront cost at trade-in time.
