We just did a bunch of shopping for a couples coach. That Grand Design Reflection 150 Series 295RL floor plan is pretty slick, we looked at it in person, the interior wood was a tad dark for us so we looked at The Winnebago 27RLTS and 27REOK. I can't speak to the quality of them, but the floor plans were roomy for such a short coach. I have seen a few people say the Arctic Fox seems well built, but I personally didn't find a flooplan that met our needs.
Basically, we found if you want a superslide, or opposing slides under 30 feet there are not going to be many choices.
