Don't buy another truck and take the money you would have spent to get the other(s) running properly, that would shut everyone up. Girl would be happy you don't have "another one" and your family can kiss it when you get your trucks going properly again
...ORRRRRRRRRRRRRR...
sell everything you have now and buy one that someone has already gone through. Like a 3-5K home built truck with a new/rebuilt motor/trans, they're out there.
