We just got back from a 400+ mile trip with our 5th wheel and found that a lot of unburned fuel had blown into the bed. We remove the tail gate while towing. Also, a lot of fuel streaks are on the front of the trailer. My question is this: Is it normal for unburned fuel to be thrown out the exhaust on the DMax? I have to assume it came through the exhaust since it had a lot of soot mixed with it. Also, milage has dropped drastically. On previous tows from St. Louis to Bristol, TN, I was getting about 11.5 mpg. On this trip, it was only about 9.7 mpg. I would take it to the dealer, but all the mechanics are on strike in St. Louis area. Any ideas?
Thanks for any replies.
Bill
