Yes...Dodge did make 4 door trucks in the 90's, but they are called Quad Cab's, not Crew. The "Crew Cab" is the one with the smaller suicide style doors in the back ;) ...just an FYI :cheers:
Personally, I would trade up to a Diesel to get the better MPG. My 4.7L Ram gets about 12 MPG right now and the Diesels are getting 19 - 23 MPG from the guys that I have talked to around here. That is definitley worth the change even with the price of Diesel fuel being what it is I would save about $120 a month.
I have never been a GM type. Dodge is always my first choice, but I really do like the old Fords wit the 7.3's.
