Everyone is different, but my experience with the couch and table is the opposite. Our table is on a drop hinge attached to the wall with a single folding leg. Takes about 10 seconds to change the dinette booth to a bed. The jackknife sofa equally as fast. We store sleeping bags and pillows under the sofa, so setting up the beds is very quick. Our 22ft ball to bumper has 4 sleeping spots, a double with single bunk over, the dinette bed, the couch bed. None of the kids has to share, and once everyone is awake it is only a couple minutes to stuff the sleeping bags and convert the beds back. It is at least worth looking at models with it and playing with it to determine if it does or does not work for you.
As stated before, the bane of 1/2tons is cargo / payload. They can haul a lot more than they can carry. You will only get close to that 10,000lb rating if you are towing a boat with 9-10 percent tongue weight. A 10,000lb travel trailer will have around 1400lbs tongue weight! General rule of thumb for 1/2tons is 4500-5000lbs dry which averaged 6000-6500lbs loaded and about 800-900lbs tongue weight. If you stick to 4500-5000lbs the numbers almost always work out.
