Tire & Axle Question
:@ I don't get it - am I wrong? Why is it the larger RV trailers have two/three axles and four/six tires? To me it would make more & better sense to use a single heavier-rated axle and, if needed,...

There is no such thing as equalization or load sharing on a single axle.
You are correct.
The single axle doesn't have the equalizer, but a single axle rubber torsion axle will usually ride better than a single axle leaf spring unit. The single axle doesn't have the problem of scuffing tires like the tandem or triple axles. The main reason for the multiple axles is because the trailer frame isn't strong enough to be supported by one axle.
A tandem, leaf spring axle, of the proper weight rating is hard to beat.
Could a single, dual axle work well for a heavier trailer? Yes, but the frame would have to be much stronger and the load on the TV would be greater to insure proper tongue weight. A single, dual, rubber torsion axle trailer (especially in the 7000-8000# rating) should tow real nice with the proper tongue weight and it would have the benefit of the second tire on each side to help if there is a flat.
It just isn't popular, but it would work. Remember, you would need a heavier front jack and good stabilizer jacks.
