At 4000 for a used tank that’s steep don’t think you will get that to be honest. Used tanks don’t hold value
I’ve read your comment multiple times but I can’t make out what you’re trying to say... I paid $6000 for the tank set up. No where does it say $10,000. After equipment I have well over $10,000 invested
For a used off the shelf tank you are right but this is custom bigger tank. I’ve had multiple offers as of now but logistically it hasn’t worked out. I appreciate your concern for selling my tank but if you are not interested just move on.
