My only complaints about my Bullet 21RB with opposing slides were I couldn't get to anything but the bathroom (including the stove, sink and refrigerator) when traveling. The refrigerator was in the slide so the top vent was in the wall instead of the roof which meant the fan ran A LOT which used a lot of battery when I was boondocking (5 months of the year the two summers I had it). The extra breakdown time to clean the roofs of the slides before retracting them. And the extra cost and battery power to heat the camper in cold weather. Basically, you have three inch gaps around each side with just the rubber seals. That adds up to about nine square feet of wall with NO insulation for two slides.
