another way to get info, while you're waiting for other Surveyor owners to post, is to do a search in the Surveyor sub-forum, for those particular models.
i do know that Surveyor did some recent changes to their lines/models, so not sure if those models you're asking about, were called by different model names or model numbers, previously.
