I purchased a Dynamax 32KD. It has 100 gallon fuel tank which will fill only to a certain point (not even half full) then you must "trickle" in the diesel. To fill it from 1/2 full to almost full yesterday, it took 45 minutes. This is annoying not only to me, but to other service station customers. Not only that, but am I (a 78 year old woman) going to be happy standing out in the cold/wind/rain for an hour, trickling diesel fuel into the fuel tank? I think not. What is the problem and how do I fix it so that I can fuel up the MH in a timely manner? I tried removing the fuel tank cap on the opposite side, but the improvement was negligible.
 
Welcome to RVforums from Ely Iowa. Have you tried to adjust how far in the filler tube you place the pump? Also are you fueling at the auto pumps or truck pumps? Try using the truck pumps and dual fill pumps.
 
I've tried both auto and truck pumps. Same problem on either one. No, I have not tried filling from both sides, but will do so next time I'm out and need fuel. I've written to Dynamax about the problem and will share their answer if/when it arrives. A trucker told me it was because that when filling, the fuel level has to equalize between the tanks. That makes sense, but regardless there should be a way to fill faster.
