I have a Postgresql 9.1 database that is being hosted by Heroku. It currently has a read-only "follower". I need to truncate several large tables (over 100GB) of data and reloads them. Is the read-only follower going to cause an additional overhead to this operation? Should I drop the follower and recreate it after the process is complete?

Truncate should be a logical operation that should not be too bad disk I/O-wise. I would not expect a lot of problems there.
