Congratulations on your first Camper and welcome from NJ. That's a pretty lookin Rig right there! Enjoy it!
I don't want to sound like a critic here but I was in a similar situation with my last Truck/Trailer combo.....If your not planning to upgrade the Truck in the near future then I would like to second the recommendation from Biggles, I used Airbag helpers in my old pickup and they leveled out the ride tremendously! Ride is much more smooth and stable plus the rear doesn't bounce for 10 seconds when you hit a pothole.
Aside from my 2 cents.. Enjoy your new Camper and many Safe and happy Travels!
