Going by this chart from NO-SHOCK-ZONE you can see what the measurements should be around your 50A connector using a multimeter...

Using a RV50A (M) to RV30A(F) adapter cord will look like this...

Note that only one leg of the HOT1 or HOT2 is used... This will not feed 220VAC to the 30A Trailer. IT will however feed 120VAC at 50AMPS to your 30A Power Distribution Panel but you will be protected by a 30A Breaker if you draw more than 30A's from your appliances...
I have no idea how this would affect any surge protection devices you may have hooked up protecting your 30A Power Distribution Panel...
I guess this all makes sense to you... I would contact a RV Wiring EXPERT if you are unsure about anything... I am NOT an expert in this area... Just reading all of this from the NOSHOCKZONE on the internet...
This will be no different than using the RV50A(M) to 30A(F) adapter Cord connected to the campground pedestals... I do this all the time as when I look at the contacts on the 50A connector they all look like new as compared to the 30A connecters that have black burn marks everywhere haha...
Here is another drawing from NO SHOCK ZONE showing how to wire up the 50A and 30A connectors...

Here is pictorial of what to measure around a 30A Connector using a multimeter...

Might be interesting to compare notes with you just have connected up...
