Congrats on your 212BH! We have the same trailer and so far so good!
As others have said, a good dealer will look after you.
Only had a minor issue - the 212BH only comes with a CD player - not DVD - so I asked them to swap it - they did, but with a Car stereo DVD player.
There was no remote and the DVD would play as it said "parking on".
It expected to have a parking brake circuit.
So they messed that up.
Long story short, I said I wasn't happy with it, so I removed it and they gave me $250 back.
I ordered a Jensen AWM 975 which I will install myself.
