Yea took off all the mud flaps the ones in rear could have fit but it looked weird with just those left on took the truck for a road trip still getting decent mpg . I’d say I lost about 1.5 to maybe 2 combined . I haven’t done the calculations.
Drove it around the last two days city cruising and then made a trip down south so went through a half tank and still maintained 18 so that’s good enough for me [emoji2]
