True confession: I've owned a 2007 National Tropical since new...that's not the confession. I have had extreme difficulty refueling this coach since it was new...That's clue number one. I have read here and elsewhere that folks have discovered the fuel tank vent hose coiled above the fuel tank. Well, this past winter I got soaked refueling in a rainstorm ( it took me almost 45 minutes to fuel up about 50 gallons). Now the good news, Altrui Truck Sales, in East Providence, RI, dropped the tank and corrected the problem. Today I successfully added 74 gallons in approx 10 minutes. So, when you hear of a fix on this forum - - take advantage of the knowledge base...I'm a happy camper with a full fuel tank and I'm plotting my winter trip.
