I'd be curious to know the answer as well.

I hope someone will correct me here but my impression was that the 2619s rarely or never had a slide, the 2417/2518 only had slides in the newer models (post 2012 or so?).

The 2922 has 'always' had slide models available, but since the entire 2922 line is fairly new, you won't find any older slide 2922s. I can't comment on the 3326 because that was out of our towability range. Definitely some 3023s had slides, but those models were very uncommon when I was looking.

Since we wanted a king bed, wanted space for a recliner, and we couldn't afford the newer models, that narrowed it down to the older 3124ks series for us, even though we'd eventually like to go smaller.

Best of luck.
