Was shot down on the option of changing out the receptacle at the rental unit.
I have found some Nema 10-30R to L6-30P adapters but it seems that the prongs don't match even though by name it should.
Are there any websites that I should be looking at? I've tried ebay, amazon so far
I'm sure the landlord said "no". Just a couple screws. Should have just changed it out and replaced it when you moved as suggested above.
