I had a 2004 Lance 1161 that I used for many years and recently traded in for a 2014 Lance 1191 with the rear tent option. It has a queen up front, the tent is a queen, and the dinette makes up into a short queen (~ 72x58). We also have the bunk option over the dinette which is ~ 72x34. That's a total of 7 people, but it's over 5K pounds loaded. I carry it on a 2000 F350 Powerstroke Diesel with 19.5" H rated tires, Rear Supersprings, Rear Timbrens, Front Sumosprings, front Helwig 1.5" sway bar, rear Roadmaster 1.5" swaybar, and Monroe HD RV shocks all around. The truck carries it very well.
I have an 11 year old and we wanted her to be able to bring friends with her. We've had the camper for 3 months and we love it so far. The new slide is much deeper than the previous 1161 and it makes for a much larger dinette and a much larger open floor area. We have a 24" TV and Wii U mounted on the rear wall that separates the tent area from the bath in addition to storage hooks, cup holders, several mounted soft storage baskets. The tent has a heater vent that helps in cold weather. We were on the Mogollon rim last weekend at about 6000-7000 feet and it got down to 35 degrees. I had the heater set to 60 degrees and it kept up with it well.
