DO NOT TOW IT! Do not tow that way. It is crazy dangerous and insurance may not cover it if you were to have an accident. x2 on the trailer tires, but if the axles are bowing up that much, you are over weight. Move some stuff to the inside of the RV. I assume we are talking your enclosed trailer issues not the Uhaul trailer. The Uhaul trailer should be just fine for hauling the VX. They are pretty good about setting up the right equipment for liability reasons.
You can unpack your trailer and put light stuff in the front, heavier in the rear, just make sure you don't go too light, it will cause the trailer to porpoise behind the tow vehicle (that is where the trailer is wagging the dog so to speak).
