Looking at a gulf stream conquest 255 with slide out and a 25lx heartland prowler no slide out. Rest of the features are about the same. Price the same. It's me my wife 2 girls 7 & 10. Plus two big do...
I towed my TT from Utah to the East coast and back. I purposely looked for a TT without a slide. I liked the idea of the structural integrity of the "single box" and one less thing to go wrong.
Slides can be troublesome as mentioned-but the trade off is the extra space.
