I will say, there is likely not a vehicle, nor trailer, as crazy as that seems that meets all your personal particular needs or wishes.
Sounds crazy, as there are soooo many different types of vehicles and trailers available in virtually every configuration. But based on your current and past posts regarding this, I’ll go out on a limb and say that nothing will be acceptable compared to the ultimate rerod package that you are imagining or wanting.
