So I heard GM is offering 0 percent on the HD trucks. I see that the 4x4 CC w/t and custom and some LTs can be had for 45K. My current 05 2500 has 226K on it and has asked for nothing but a water pump and knock sensors. Due to work is only saw 2500 miles last year, will be the same for this year. I say that making a payment on a truck I don't drive is just wanting something new after 16 years and to keep the old tow piggy. I have no bills other than camper payment.DO I toss money at the piggy when it wants it OR do I get ok money out of the piggy for a down payment on the new truck?
