I was in the first 10 on the pre-order and got no emails past the measurements on this. That's great to hear it's a good product as I was helping the hype early on! Now my view is the company matters more than the product.
Dorman products are great. As with any replacement part, a lot of times people do not replace the related parts along with the main part. Old related parts will put extra stress on the new part and cause premature failure regardless of the brand name.
I have had the Dorman on mine for 5 years and running, it has been great with no leaks. I also put one on my 25 f-150 on the first oil change. I have sold many of these and have never had a customer come back and complain!
I was in the first 10 or so on the preorder list, and all I ever got was the email about the measurements. I can find other places to spend $800 who care more about customers! Glad to hear you like them though!
The oils changes are simple on the 2.7, as there is a hole to drain down. All you need is a drain plug like the dorman where you can just open it. I did have it on when I had the plastic bumper and it fit great.
