I am looking to trade in my 1/2 F150 for a 3/4t diesel to pull my 8k 5th wheel. This f-150 doesit now, but has no long distance capability. It needs to be an automatic for ease of use. Any thoughts would be appreciated. I am looking at the ford & dodge line..have read other discussions on this, but they seem to be addessing the current 99-02 line...this would be my 1st diesel, so i want to make the right decision..thanks in advance..
