I have been lurking for the past year! I have read all the information I could find. I am going to upgrade to HDT as soon as the wife and I retire in the next year or 2. I have not been able to find information on if singling a freightliner is possible or not? Yes I know the Volvo is easy but the cost of used trucks is going up because of cali emission laws. If someone has some in site please share it with me.
