Adding a 220 volt panel question

We have a travel trailer with a 30amp, 120 volt panel and supply.
I am planning on installing an additional 220 volt, 50 amp panel and supply, (I want to feed a clothes dryer).
Do any of you electricians or electrical engineers know if having two supplies is in compliance with the national electric code ?

My plug in post has both plug in receptacles and I own it, and it is fed from a 100 amp breaker.

    I'd say no, but will let others more familiar with the code comment.

    Updating a 30A panel to 50A can also be expensive. Instead replace the 30A cord with a 50A cord feeding a new 50A panel located anywhere you like. One 30A breaker feeds the existing panel which is now a sub panel to the new 50A panel and a dual breaker feeds the dryer.

    I only recall one other poster that had a 240V dryer.
