I'm assuming you've not owned a Sprinter based rv before. I didn't either until I bought a new one last year. Check out carefully the issues you would face when you become a Mercedes Sprinter diesel owner. I was really surprised! Things like dealer service in an emergency or for routine maintenance can take weeks to get an appointment assuming you can find a Mercedes dealer in the area that will work on Sprinters. My 2018 rv on a 2017 Sprinter needs to have def fluid and uses it at the rate of one gallon/1,000 miles and, contrary to what others say, can be hard to find and messy to fill when you are on the road. Routine maintenance will cost you really big time like $500 for a front end alignment; $1,000+ for a new windshield; $235 for a fuel filter you change at the first oil change.I've paid all this! Other concerns are, and all the newer Sprinters have this problem, a brake pedal that sinks half way down to the floor before any stopping occurs. Of course there's the issue of the diesel fuel. Messy, smelly and to make matters worse, you have to open the driver's door to fill the tank so the fumes can permeate the cab area. On the Sprinter Talk site 50%+ of the people who own Sprinters stated that they would not recommend to others to buy A sprinter and feel they've made a mistake. By the way, my fuel mileage on a 22ft class C is 14-15mpg on the open road doing 70mph.
