Who has a new engine?

I'm getting a replacement engine and I'm wondering about it. I know a number of people on this forum have put a second engine in so I'd really like to hear from them.

Questions:
What kind of warranty did they give on the new engine?
Did you consider an additional full coverage MoPar warranty extension for 5/100K miles? If so, why or why not?
Did you keep the truck or decide to trade it?

What things surprised you about the new engine, good or bad?

Thanks for any feedback you may provide.
