I can agree to a certain extent, but there is always room for improvement on a design, and BPD has done so. I do all of my own maintenance and have an Edge Insight as well. I have been keeping up with the threads on the BPD/oil coolers/EGR, etc. and ended up purchasing the BPD kit after learning the cause and effect of how all of the systems work. I am anxious to go ahead and install it because my EGR is starting to fail at 158K, and my deltas are ranging from 5 to 30 degrees unloaded. So, I will not risk towing my race car with the current numbers.
I went back and forth trying to figure out which route to go - BPD kit with oem cooler, EGR delete, in addition to a coolant filtration system, or the full BPD package. Since I will be towing a race car around the country, I cannot afford to deal with a freak failure due to the oil system. I figured it would be cheaper for me to spend $2K now rather than in the middle of somewhere with a broken truck attached to a trailer and car. I would imagine the latter scenario would be much more expensive and would easily overshadow the cost of the BPD system. Additionally, I think it is just a better design that will qualsh all fears of EOT and ECT deltas having to be within a range, as well as reduce the amount of time staring at the Edge Insight while towing.
In a nutshell, the BPD system takes care of the major weakness of a 6.0. Basically, it is eliminating many of the problems that will trickle down such as the EGR cooler, larger contaminants, high operating temps, coolant restriction, or the mixing of the oil/coolant. So, it makes sense for the long haul and for persons that will be using the truck for what it was designed for. That said, I took the same approach you are taking on my BMW 525i with the radiator. They are known to be weak on the plastic parts, especially where they mate up to the aluminum. I opted to go wit the oem instead of the all aluminum which was quadruple the price. It is very easy to change out a radiator on this particular car and it can be monitored fairly easy. However, the same cannot be said with the function and accessibility to the oil cooler on a 6.0, especially while towing out in the middle of nowhere - the damage will be severe if it occurs.
I am relatively new to the 6.0 world, but not wrenching. My main experience is from working on BMW's and Porsche's. I actually think the 6.0 design is pretty nice and most of the problems in the past was a mixture of poor maintenance procedures due to an advanced design at the time, price gouging of parts (oil/fuel) by Ford forcing consumers to use aftermarket garbage, and poor oil lubrication/cooling. The first two have been taken care of over time, now the third has a solution from BPD. Every single car has it's own weakness and it needs to addressed for longevity and this seems to really "bulletproof" the 6.0. Problem is, not everyone can afford it.
