You are probably going to be overweight with the more involved floor plans. The next question is what are you going to do about it. You just bought a truck, so I'm assuming you are locked in on it.
You can either go to upgraded wheels and tires and make do, run over knowing you are over, or go with a lighter camper. If it was me, I'd go for a rather basic camper with a more open floor plan in a used model instead of upgrading the truck.
BTW, I carried the camper in my signature on a SRW. It's doable, but isn't quite a solid as a bigger truck with better brakes like my F450. There are more open floor plans available at least in older models. Look for one with a very long u-shaped or l-shaped dinette. S&S and Northern Lite used to make them. We ended up going with a double slide, but both of those companies and floor plans were close.
Here's a look at the old floor plan for Northern-Lite.
'10 Ford F-450, 6.4, 4.30, 4x4, 14,500 GVWR, '06 Host Rainer 950 DS, Torklift Talon tiedowns, Glow Steps, and Fastguns. Bilstein 4600s, Firestone Bags, Toyo M655 Gs, Curt front hitch, Energy Suspension bump stops.
