Think we have found it....Grand design Solitude 365 DEN

That floorplan would definitely give you the room your family needs to live in it for months at a time. The den is very spacious in the sofa position and would make a great play room for all the kids toys. The quality in Grand Design is not disputed! A half bath for convenience! Beautiful interior layout with island kitchen, 2 TV's and fireplaces.. NICE! If you can get a rig powerful enough to pull that beast with a 3200 tongue weight-- Go for it!
