The amp "draw" will determine the amount of energy you move along the path. So if you don't draw more than 15 amps, you will be fine. Check your appliances and whatever else you have within the trailer and confirm that all in combination does not exceed 15 amps when in the "on" position.
Also, do you have a breaker or fuse along the path that will trip when you exceed 15 amps of draw? An example might be a shorted out appliance that will draw an infinite amount of power if nothing tripped along the way. This should be a safeguard you have in place regardless of the amp service you plug in to.

No, that's probably not much power. But as BW mentioned if a hot wire happens to get shorted to ground somehow, it will draw current until a breaker trips, a fuse blows, or something catches on fire. It's good that you have that breaker to prevent a fire.
The cord being used to connect 62ham's 15A plug to a 30A adapter, will likely not be rated appropriately. Typically 14 gauge is used for 15A and 10 gauge is required for 30A. If the draw exceeds 15A through that 14 gauge cord, things will melt in a hurry.
So in a nutshell, unless 62ham has a 10 gauge cord connecting to his trailer, a 2nd 15A circuit in his trailer would not be safe, or to code.
12 gauge is good for up to 20 amps, so you're fine for 15amp service. But if you upgrade your inlet to 30amp in the future, you'll need to get a 10 gauge cord and run 10 gauge wire from the inlet to the breaker box (because it's likely 12 or 14 gauge as well).
