we have the conquest deck. Three kids 5, 7, 9 nobroblems. As you said just cant haul ass, you are carrying presious cargo. Decks are great for the kids because of the entry IMO. You don't really worry about them scracthing it up and dthe storage is WOW. As you know with kids you end up bringing everything.... They will have fun on anything as long as they are there.
Be safe and good luck.
