Welcome to the forum and to the club, Jim.
I highly recommend retirement, it's the best job I've ever had.
My pop up days are a distant memory, they predate the crank up lids and built-in appliances.
It was more like a tent on a trailer, than a fold down camper.
You have plenty of tow vehicle for a pop up, the first thing to do, is identify where all the stuff you need and use most will go. Then add the like to have stuff.
I have a Good Sam membership, it's good for a 10% discount at participating campgrounds and a discount at Camping World. I rarely use it now days, as we are more into boondocking than the campground camping. We just pick a direction other than west, to point the truck and go.
When I was a kid I was going nowhere fast, now I'm an old man I'm going everywhere slow.
