One year, 15,000 miles and just more of the same
I know that alot of you are thinking, 15k big deal, but in an rv (E450 chasis) 15,000 miles in a year is quite respectable for two working people.
Our very late model year '07 6.0 continues to run flawlessly, no oil added between 4k or so changes, coolant remains steady in the overflow bottle, no glycol shown in oil analysis, the STOCK power and speed is beyond enough for any sane person and high ambient temperature operation continues to amaze me, temp gauge just doesn't move from normal-but man can that fan make some noise when its moving at full tilt. Fuel consumption remains steady at 14 mpg when pulling our enclosed utility trailer with the bike in it, add another two mpg sans trailer. Doesn't sound like it is all that great but again remember its an rv, a gasser in a similar rig is using about 50% more fuel-gas rv's should be illegal, seriously.
A winner in every way.
