Update from OP:
Now that the truck is ordered, I have done a little more study on what I can handle regards trailer weight, pin weight, as advised.
Payload max on that truck is 3,770 including passengers. 5'er towing limit is 16,200. I note that the Excel/Peterson's are quite heavy, so they're out.
I started looking at the Grand Design Reflections, and their specifications are well within my specs and, equally important, have the amenities that DW wants. Also, equally important, is their price range and available options.
Others have commented favorably on Grand Designs, so I feel like I'm really zeroing in.
I want to, again, thank everyone for their thoughtful guidance, and I continue to solicit more.
