Pix look good and the XYL looks happy.
How could you ask for more???
Most of the rigs we have had were 5th wheels from 24'-39'. We had 5 of them over the years.
Now it's a MH. Getting older and even the ease of setting up the 5th wheel is a bit much for the older set with a bad back in the mix.
We had about the same truck as you. An '05 with the 5.4, 300 HP and 3.55 gears. We got 10-14 towing with it with the last rig at 8200#. It was a 4x2 and there were times we wish we had the 3.73 or 4.10 gearing but we liked 17-20 unloaded at a fast cruise.
Enjoy the new rig and camping. We got out of tents in the 70s with our family and really enjoyed it over the years.
We started with a small MH, had two tent trailers, a standard trailer and 4 5vers over the years. Now it's the big MH. This one we will live in for a few years in our travels if we are lucky enough to find a buyer for the home someday.
