Time to give up my DW, I mean DT (Dear Truck)?

Just the fact you brought up this subject tells me you are ready for a new truck. So ... go for it! If you get a brand new one, you'll get all the free warranty service contracts, repairs, and all that won't have to worry about anything for a while. Once you have the new truck ... and you WILL be getting it ... you'll wonder why you didn't get it sooner! New trucks are NICE! Go for it. You've already made up your mind, you just need to accept that now!
