People don't bother to look at the COG range NUMBERS on the camper loading sticker in the glove box of their truck (or in the owner's manual). They just look at the pictures, and see the narrow black section centered over the wheels, and ASSUME that the COG range is very narrow.
On the last 3 trucks I've owned, the numbers indicate that the front of the COG range is the VERY FRONT of the bed, and the rear of the COG range is the VERY BACK of the bed.
They use complicated terms so it can be confusing, but the front of the COG range is often listed in terms of inches from the REAR of the bed, and the rear of the COG range is listed in terms of inches from the FRONT of the bed.
The COG can literally be ANYWHERE in the bed, and be ok, according to the manufacturer!
