Having owned a pop up and a TT now i would go the van route forst. You have 5 people and a dog. So you need beds for everyone. I would look into a double bunkhouse TT. I dont see you having the room in a motor home. The van will give you room for the familly and the dog. The TT will have enough room for everyone, but will still be cramped. Less so the the pup, but you do have a lot of people. The van can also be used when your not camping. So thats a plus. Your not taking the class a to do the weekly geocery store runs! Just what i would do. Its your money. But tbh i think some of TT are more suited to a larger familly then the mid size/ smaller class a.
