Here are the specs per Keystone on the Hideout:

It's a 7500lb. gvw trailer and 29'3" length ball to bumper.
I'm just going to make a couple of observations;
A 29-30' trailer is not a good companion for an Armada. It's a vehicle meant for "towing" a large family.
If I have interpreted right, the truck weighs 6360 at the scales vs a 7150 gvw. That was without the family, luggage, toys etc. so when fully loaded it will be pretty close to bumping max gvw.....with a 29-30' trailer behind it - it's not going to be easy to control in adverse conditions. And, if you deduct a 15% safety cushion from the gvw you would have 6077 lbs.
And....the trailer is not fully loaded either.
Then there's the receiver.....and completely maxing out/overloading the suspension on a 9 year old SUV with a 29-30' trailer sailing along behind....and,.....and....
IMO it's not a good idea even if you could squeak by the numbers
realistically, which I doubt. Trying to "go light" with an 8 year old on any length trip is a pipe dream - especially when you have all the room in the trailer.
