Regarding Consumer Reports:
I have used them for 40 plus years .
I use them as a source to get educated about every product they test .
I have followed their articles for cars and trucks and have had good results .
Why would I disregard Consumer Reports in favor of some person on the internet that has way less actual experience in comparing two or more vehicles ?
For those that have the combination of duramax / Allison with a 3.73 or lower ratio , they still have a grin on their face after coming from any gasser including all the Big Blocks that I have owned for the last several decades .
