OT: ATF flush for truck?

What maintenance service has the truck had in the past? If it has been serviced regularly, then an ordinary fluid and filter change should be sufficient. If this service has been neglected, then save your pennies for an overhaul. There is a substantial amount of fluid retained in the torque converter during an ordinary fluid and filter change. However, the factory recommended service interval takes this into account. A power flush is not a substitute for doing things by the book.
If you have reason to believe that the transmission is all gunked up inside, then you could do the equivalent of a power flush, by changing the fluid today, and changing it again in a week or so.
