I think y’all should buy gasser HD pickups and convince everyone you know to do the same and encourage them to convince everyone they know too.....
Then maybe the price of diesel trucks will go down with their lack of popularity. And diesel fuel prices too!
The 1000s of pages of banter here and everywhere about this is just evidence that the OP should do a lot more reading and less asking.....
One objective reason if buying a used dually though, is how many used gas duallies are there to choose from? There’s no selection so good luck finding one....
The hidden message is there’s a reason WHY the diesels our number the gassers 100:1 or more.
