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...
We had our Sunline with one slideout and it worked flawlessly for 10 years except for one time when a ground wire came loose. It just took a minute to tighten the ground wire and all is well. Our Minnie has one slide (Lippert) and it hasn't given us any problems. The extra room provided by a slideout is worth it in my opinion. But....it's a personal choice....lots of folks do quite well without one!
