03' Dodge 1500, 4.7L

[Jeff Dunaj]

I recently bought my truck and 5th, then went on a 4 day weekend.Loved everything about it. Somethings I want to improve on;
1) Just to stiffen the rearend, I want to add 1500# helpers to my leafs
2) I am considering a cold air intake and/or chip to assist on big hills.

Are these worthwhile, I managed 11 MPG at 75MPH with a 23ft 1985 Komfort 5th. Just wondering if these are worth the money.
