That's what the dogbone adapters are made for. I do it many times, since one of the campgrounds I frequent also has bad/loose 30 amp outlets, being they are used a lot more than a 50 amp outlet.
Your actual TT can draw no more than 30 amps, due to it's main circuit breaker in the travel trailer, and if it functions as it supposed to, would trip if overloaded... thus protecting your travel trailer.
However, since you are plugging into a 50 amp outlet, your tt's power cord would be able to have 50 amps go thru it....since it's now between the 50 amp camp ground pedestal circuit breaker and the travel trailers 30 amp main circuit breaker.
You really shouldn't have a problem with the cord when hooked with the dogbone adapter, especially if you use your trailer as you would have if hooked to a 30 amp outlet. You would have to have your TT's main circuit breaker fail to function, and also have more than 30 amps (but less than 50 amps) worth of things turned on in your trailer, before the cord would have more than 30 amps going thru it.
