Ford diesel 97 powerstroke info?

[deportes]

I am looking at purchasing a 97 4x4 diesel so I don't have to smog in California. I will be pulling a fifth wheel travel trailer. That is why I am considering a big monster.
What and how do you check a diesel motor for proper performance, I hear about blow-bye, I will stay away from automatic transmission because I heard they do not last and cost 4k to replace. Any suggestions on what to look for on american diesel's. Dodges are more expensive so I will stay with a power-stroke.

All info is welcome. Thanks.
