personally, i don't think they sold enough to keep making them.
even Outback, #1 in sales for rear bed slide TT's and had the most floorplans, has drastically cut down the number of rear bed slide models in their lineup.
that should tell you that, if the #1 manufacturer of this type of TT is dropping a number of the floorplans, then they aren't selling enough.
