keep it in recirculation mode and it will be nice and cold. My cuts in and out when in stop in go traffic if i'm in fresh air mode.

Yes, you can use 5W-30 in your Mega no problem. Chrysler spec'd 5W20 for all HEMI engines in 05 and 06 but 30 weight was spec'd before and after in the same engine. With no MDS 5W30 is just fine. Here are the oil spec's for 3rd Gen HEMI Rams...
03-04 = 5W-30 and 10W30 ( All Models )
05-06 = 5W-20 ( All Models )
07-08 1500's w/ MDS = 5W-20
07-09 2500/3500 less than 14,000 GVWR = 5W20
07-09 2500/3500 more than 14,000 GVWR = 5W30

I would not worry one bit about the 5w30. Different engine but I have almost 100k miles on a chrysler 3.8l that was speced for 5w20. Even a couple changes of 10w30. The engine seems just fine.
