Family of four full-timing...RV recommendations?

Thanks for the replies. I am driving a 2007 Tundra with 4.7L V8, with tow package. I think my tow rating is ~8000 lbs, but not sure. Bought the truck used and it doesn't show the tow rating on the door sticker. Still in exploration phase of planning, but we are very motivated to make it happen! We have done everything from 2-man tent camping to our current pop-up tent camper. Looking forward to making it a permanent situation.
