Rate You Truck's Reliability - Heavy Duty Diesels

I have a 2007.5 (first gen 6.7 - a beta year for emissions equip, EGR valve & cooler) 3500 Ram dually 4x4 (4:10 axle), and about a year ago swapped the Tembrens for 2 extra leafs (in the main pack) on each rear side (about $850)...Spring-wise, the installer said that it now exceeded a 4500 rating (rear), and the handling is superior with nary a hint of the loaded 4,900 TC being aboard!!

The new generation of diesels have so much torque that a 4:10 rear axle is not really necessary, JMO,
