What do you mean by "near experience"?
How many gallons of fuel did it take to fill your tank?
The manual states that the MB Sprinter based motor home fuel tank holds approximately 26.4 gallons and the low fuel light is set to go on when there is just over 5 gallons of fuel left. Even at 10 mpg, which is most likely worst case scenario, you would still have close to a 50 mile safe zone.
The time my low fuel light went on, I stopped at the next station, approximately 5 miles later and it took just over 19 gallons to fill the tank. From what I have read here, the general consensus is the low fuel light seems to go on at around the 19 gallon mark.
Remember to check your DEF tank level on a regular basis. Although it is supposed to last approximately 2000 miles, DEF can be had much cheaper when purchasing it at a truck stop DEF pump. Run out of DEF and you will be driving at a snails pace.
The MBS owners manual is really worth reading. Maybe not in its entirety, but at least the important parts, like tire pressure, maintenance schedule, tire change procedure, low fuel warning, fluid capacities and how to check them, etc. and probably the most important.
What to do if you run the fuel system DRY.
The fuel tank has been run dry.
X Refuel the vehicle.
If you drive until the fuel tank is completely empty, air may get into the
fuel system. If the engine does not start after refueling, bleed the fuel
system as follows:
X Turn the key to position 2 in the ignition for approximately
X Start the engine continuously for a maximum of 60 seconds.
If the engine does not start:
X Wait approximately 2 minutes.
X Restart the engine continuously for a maximum of 60 seconds.
X If the engine still fails to start, do not continue trying to start it.
X Consult a qualified specialist workshop.
Here is what happens when you attempt to start the Sprinter after the DEF light goes on
Three short warning tones also sound.
After the message appears for the first time, the remaining DEF supply
will last for approximately 1200 miles (1900 km). The engine can then
only be started another 16 times.
The number of remaining engine starts xx (16 to 0) is shown in the
message every time the engine is started.
It is really amazing all the information that Mercedes Benz felt was important. What is even more amazing is how few new vehicle owners ever take the time to read that important information.
