I own a 2007 1131 with the tent. It is a fantastic camper and has served our family well. We camp regularly with 5 people and 2 dogs. We have 3 kids and we outgrew our old truck camper, moved to a 5th wheel for one season and sold it and moved into the 1131. There is no way a family of 5 (w/ teens) could make use of a regular TC.
The drop down tent in the back is BIG. Two full grown men could sleep comfortably on it. The tent portion is cooler then the rest of the camper in the winter and warmer in the summer, but the furnace works just fine. I made an insulated liner out of reflectix for winter time - it helps alot. Learned this from the popup forum.
We have had 7 people in this camper (and the dogs) and all had fun. It will be our family camper until the kids are grown. The fit and finish and quality of the build on the Lance has been really good.
We have had no problem with the tent. I agree with the other poster that the tent has only been a positive. If it rains or snows on the canvas, I open it to let it dry once back home.
Let me know if you have more questions.
