How dependable are newer trucks with higher mileage?

I just didn't feel good spending $40-45k on a 5 year old used truck with 100k miles and no warranty. There was also the issue of financing. The difference in the rate and terms on a 5 year old truck vs a rebates and incentives on new was almost a wash in amortization.

This pretty much sums it up for me too.
If you are plan on keeping the truck for the long haul. Buy new and don't look back.
