Maxxforce motors do not use DEF. They meet EPA specs with other gadgets.

Absolutely no way.

2013 HR with the Maxxforce 10 engine. Uses a "regen" system without the added weight and cost of DEF. Navistar's system uses a high temp. burn of the carbon buildup in a special collector in the exhaust system. Key West trip did result in a 900 foot elevation gain on the return leg. Previous trip from Atlanta to Denver and back averaged 9.3 MPG.

On the Denver trip we got 9.3 MPG pulling the Honda. Overall elevation gain of about 5000 feet. Pulled at 55 MPH going 24 in TN with no problem. Diesel's with DEF requirements need to calculate the total cost per mile to include the DEF expense.

DEF cost is marginal. Burn rate is about 2% of diesel MPG. So on my coach I'm getting about 500 MPG on DEF @ about $2.89 per gallon when bought bulk at a truck stop.

Our 40' Sportscoach weighs about 29k fully loaded including the toad. We have an ISB 6.7 340 hp and average +/-10 mpg when traveling at 1750 rpm (Camp Freightliner suggestion) which us 63-64 mph. I would expect that your mileage will improve as the coach gets broken in.

If you travel at 62 mph or less and tour rpm us less than 1750, the Camp Freightliner recommendation is to keep it in 5th gear.

I think we are getting 8-9 mpg.We are full timers we knew knew that going in to it. I will be happy if we do not have major break downs .
We got the coach so we could travel from point A to point B and stay a month or 2 then move again.Try living this way in a car paying motels eating out not having things you need .Getting a M/H millage was at the bottom of list. Traveling with everything you own in back or under is a nice feeling,to us any way. Good luck and enjoy every day in your M/H. Hope for the best but plan for the worst
