Anyone towing with a deleted Cummins?
I have been reading and hearing a lot about the EGR deletes. I have trouble hearing from anyone towing anything substantial with one, particularly the 6.7HO. Any experiences anyone would be willing to...

The only reason to do something like that is to buy my last o2 sensor related to it. No more power needed and it is plenty fast enough. I too like the clean burning no smoke part so deleting the dpf is not part of the equation. I know the cooler part, but I don't see how pushing hot, oxygen depleted exhaust back into the engine can be a good thing.
It's not a good thing, but it is what it is these days.
It's oxygen depleted and recirculated for one reason, less oxygen in the compression chamber eliminates the NOx component in the exhaust stream, one of the pollutants emitted out the tail pipe. Less NOx means less Ozone in lower layers of the atmosphere. Lowering the effective compression ratio by having a flapper to regulate air input on a diesel engine also lowers the effective burn temperature.
