Hello and Welcome.
Nice rig. The second picture it looks just a little high but not too bad. One thing after pulling it a few times it will "settle" the truck springs. So if it were me i would use it a few times and then see how it sits.
One thing to check is the spring hangers on the camper. The newer ones have two holes. Moving from the top to the bottom will raise it about a inch. To gain that same inch you would need tires 2 inches taller.
Congratulations on the new camper. Now for the weather to get better.
