Looks like the majority of all replies agree that I need to look for a used one now and buy new just before I retire.
That is what I was thinking, but wanted to get opinions of others who have been down this same road. So I now need to start looking at a good condition used rig.
As for the Truck, I have been watching the weights of the full time rigs and there are many out there that are well within the ratings of the truck, but thanks for the input on it. We just don't want a Dually so that just makes our choices limited a little.
