I have the Ford Performance Tune so I run 93 but had been doing it for quite a while before the tune. My seat of the pants dyno tells me that the truck runs better on 93. YMMV.
My truck came with a roll up bed cover and the drop in liner. I added a bed mat that I made out of interlocking gym tiles. The soft mat makes my 73 year old knees happy when I have to crawl around in the bed.
Thanks! I still like them a lot! Only got to use them in a little bit of snow but they were fine and the wet performance is great. I lost a little bit of mileage but also attribute some of that to leveling the front end.
