Good advice from everyone so far. I have a SRW F350 and have no issues with the way it rides. It is a truck so don't expect a Cadillac soft and squishy ride but I don't find it objectionable. You may find it otherwise so the test ride is the best way to go.
I have a Northstar Igloo 9.5 with no slides. Here are my weights fully loaded: Cat scale weight with camper, full fuel, water, 2 dogs, Helen on 20170201 at Fackler, AL 12,420 pounds.

I am just under 1,000 pounds over my GVWR but under my front and rear axle WR (just barely). My tires are rated for 3,750 pounds each so I am also under my tire ratings.
I have been very comfortable with my setup - over 15,000 miles last year over all kinds of roads and terrain without a hiccup. Again, others might be uncomfortable being over their GVWR at all. There are all kinds of options to make your choice in trucks and campers "work" but only you can judge what you are comfortable with.
There is a common saying here - you can never have too much truck. Keep that in mind as you explore your options. I wouldn't go any heavier than where I am - others far exceed where I am. Keep us posted on how you end up.
