At least for motor vehicles (and I assume they apply for trailers), there are some DOT regulations regarding where propane tanks may be mounted. As I recall, it basically boiled down to the idea that they have to be within the outline of the framework of the vehicle—they cannot be on top of the roof, or strapped on the back bumper, or hanging down underneath below the vehicle structure. They do, of course, also have to be well vented on the underside (so that any propane that leaks or escapes through the safety pressure relief valve can dissipate).
If you can mount a permanent tank such that these requirements are met, I don't see any reason why it would not be acceptable for a travel trailer. Likewise, if you can safely mount a portable cylinder someplace other than the tongue, be it a horizontal or a more common vertical one, that would also be OK.
Bear in mind that a permanent ASME tank will be heavier than portable DOT cylinder(s) of the same capacity. That may or may not be of any concern in your particular situation.
