Bought a Donaldson 70050 and had it installed:
The effect of the muffler is noticeable, I have a D turbo and you could before speak loudly in the cab and be heard now you can almost do it at a normal speaking voice, at least at idle. Most of the noise now is engine noise.
Later that day I went on a road trip:
Approximately 1050 miles round trip to Crater Lake to meet up with 2 friends. Broke up the driving 2 days each way. Put a futon mattress in the back and a 2 man tent on top of that then threw in pillows and blankets. The tent was mostly to keep out mosquitoes. On the way down/back I would stop at rest stops and spend the night (most rest stops have an 8 hour limit in my area). Got a little over 9 mpg and could keep it at 60 mph on the freeway, both of which I credit to the super singles (prior to, I got 8 mpg and couldn't get above 54 mph). The warning sign in the first pic is about heavy traffic on the day of the eclipse. Second pic is a shot of Diamond Lake, near to Crater Lake.
