WELCOME! Glad to see you got yourself a nice trailer, they are so well built. I have had a couple myself and loved everyone of them. I sold my 101a1 and blessed a friend with my a2 after tuning her up. He loves it just as much as I did and likely gets more use out of it. were now running an a3 and a 416 and love both of them. I have no doubt that trailer will serve all of your needs. We too kept ours loaded up for emergencies as we've been through our fair share of hurricanes and earthquakes we understand the need to have a little back up plan.
Something you might consider if you haven't done the new tires yet is to match the trailer to the tow rig. If you pick up a set of spare rims (maybe 3) from a junk yard or craigs list you save big money. The hub pattern doesnt match the jeep, but a good trailer shop can order you proper parts or just get an adapter. On our 416 we swapped axles to match the tow vehicle how nice it is.
Our larger trailer already matched our tow vehicle, so that was handy. But that way you carry just one spare for everything and in a inch can ditch the trailer and keep rolling in the tow rig if you have multiple flats. we also found a dirty deal on CL for appropriate sized tires on our m101a3 as well, just a thought. I find for our uses the matching tires and rims is time and money well spent.
Again welcome and looks like you and the kids will love that trailer. My wife really came around when we moved and when we go camping. Allows us to bring what we want to be very comfortable and saved tons of money on the move. Also like you mentioned loaded and ready to go provides a whole lot of peace and comfort, just hook up and roll out.
