I would be more concerned about any kind of damage during transport, not likely but you never know.
We bought our's sight unseen from several states over, luckily for us all went good, we didn't know half of what we know now, we got lucky all around. We got a good unit, found a great Mom and Pop dealer that has been great, very close to home. From all the horror stories I feel good about our's.
I hope your experience goes as well.
