my Jayco 24rks is very similar to myredracers rk TT. the main difference is the wardrobe and fridge are not part of the slide out, and the slide is not quite so deep. no problems using trailer with slide in... in fact over Thanksgiving, I used it with slide to conserve heat/propane by having less outside surface area on N side during freezing nights.
as to location of bath, I bought my TT because it had the mid-bath. I really disliked having to go past adult son on sofa to bath room in the middle of the night, when he was with me. Wasn't a problem when I was alone, but when I had someone with me, it was something I was uncomfortable with.
