For easily configured storage above knees, look at the plastic drawer units. Granted, we have a highwall that fits nicely in the garage and got it used so it was $7k a few years back (not sure why you're ruling them out), but here is an example of how to gain above knee storage.


I had looked at making a wooden platform to go across the top of the plastic shelves so there would be a level, stable place to put a TV, etc but we opted to not have TV at all. Different strokes for different folks.
If you're looking at frozen pizzas, even the 3.7 cu ft refrigerator in mine that has a freezer cannot hold a pizza as it is not deep enough. You'd have to fold the pizza in half. It's great for making ice or having small tubs of ice cream and popsicles.
Otherwise, my highwall has everything you've listed as a want or need. The real porcelain toilet has an onboard holding tank that you empty at the dump station and is supplied by the fresh water holding tank and pump or city water. The one thing I wish it had was an onboard gray water holding tank. Still have to use a blue tote for that.
It has a cable TV jack on the inside and out. Plenty of full height counter space, too much storage that we don't fully use and all the comforts of home.
My V8 4Runner pulls it just fine and I can still position it by hand in the shop to get it over against the wall.
It did take me a while to find it.
