Oh cool! I've always wanted to see pics of that one up close.
Notice the Energy Guide label for the Danby top loader. The little arrow is just off the charts to the left, which means maximum efficiency for its size.
Yes, that dark gray panel that's sitting on top is called a mouse-proof or a rat-proof in the Asian markets. Presumably because in the rural areas in those climates, mousies are known to make their nests in the workings of washers. For the USA market it's a noise-proof because no one in the US admits to having mice

In Australia what you have to worry about is venomous snakes and spiders, which are so lethal they make ours look like cuddly pets, but somehow I don't think manufacturers want to call that panel a snake-proof down there.
Optional swivel casters. Hmm! I wonder if they have locks or stops. On the twin tub the casters are built-in and non-swivel but it's still easy enough to move the machine around the kitchen. It would make sense to have non-swivel casters on a conventional TL because the axis of spin is symmetrical with the cabinet, and so it's more likely to scoot around the floor. In any case you do have to level the machine before using it, and might have to adjust the leveling if you don't use it in the same place each time. Also on the twin tub there's no need for leveling because the fill level is controlled manually from the faucet and the spinner is not symmetrical with the cabinet in both directions.
The agitator is almost identical to that on the twin tub, but on yours the side fins are a little deeper. On the twin tub the top thingie unscrews a quarter-turn and removes for cleaning the lint filter; on the TL you might have a lint filter system built into the washtub. The way the agitation works on the twin tub is similar to a pulsator or the Whirlpool compact "pulgitator." One turn clockwise, pause, one turn counterclockwise, pause, repeat. One turn each way in "gentle" cycle, which is strong enough to clean most anything. Two turns in one direction followed by one turn in the other for the "normal" cycle which IMHO should be labeled "strong" because it is, and also tends to be somewhat splashy. I'd be interested to know if the same system is used on the TL. What I think Danby did here was: these would be pulsator machines in Asia, but for the North American market Danby had conventional agitators fitted because that's what we're accustomed to and they won't tangle pants legs and shirt sleeves.
Actual full load capacity on the twin tub is 75% to 80% of rated capacity, so the TL is probably similar; to be safe you probably want to start with a load of 60% of capacity and then try 80% and see how it goes. For blue jeans, roll them up in a loose ball before tossing them in; they'll unroll while washing; otherwise they tend to take up more space than necessary and reduce capacity.
Two input hoses are intended for permanent installation; when used as a portable and attached to the sink, you use one hose and control the temperature from the faucet: so if you want a warm or hot rinse, you can get it.
The galvanized metal back-panel has sharp edges and may tend to rattle a bit during spin. The way to solve both of those problems is to remove it and line the edges with folded-over duct tape, one layer is quite sufficient; and then screw it back on. The duct tape cushions it enough to stop the rattle and of course makes it safer to handle. Don't over-tighten the screws, the sheet metal is somewhat lighter than we're used to here and you don't want to strip the holes.
If you do turn the machine on its side to install the casters, it would be interesting to see photos. Ditto for if you take off the back panel as per above paragraph.
