Over the last 4 years we have purchase RT tickets that extended 60 & 90 days and have never ever been questioned by customs or for that matter no one else. We've been told that immigration could ask to see your return ticket when renewing your 30 day stay, but again never have been asked when renewing.

I'm happier than a pig in s__t...a foot on the sand...and a Belikin in my hand!
