Hello, reading and learning. Own a 2011 1 ton dually Cummins but time to down size. Test driving an eco diesel 1500 ram quad cab tomorrow but find the sales people product knowledge is limited at best so will put forth questions here. May order built an SLT Quad cab with 3.55 gears. What's the difference between the express and SLT? 3.55 Gears best for fuel economy? I'll be towing an 11foot tall 5k lbs travel trailer once per month for about 380 miles and with one cross country round trip per year west coast to east coast. Rest daily drive. The transmission is an 8 speed automatic but I read of people shifting gears? My 1 ton has a G56 manual so shifting not a problem. So my questions;
Express vs. SLT?
3.55 gearing best economy for 5k lbs?
