HP numbers are misleading as the 6.7 HP is more than your ISC...arrived at by turning the 6.7 2800 rpms instead of 2200 for the ISC. The good news is the torque is only 200 ftlbs less than your ISC. Also, the pollution systems problems have gotten fixed (2010-2014) and DEF is readily available.
When upgrading 2 years ago I was not impressed with the quality of new rigs, but I was not looking at the smaller rigs. Ended up going with a 10 year old rig which has worked out well.
*Now that I see the above post by Larry...he sums up my thoughts about the rig you know and what’s often referred to as “the new MH blues”. Hopefully the smaller new rigs have not gone to advanced electronics to control everything.
