First, welcome to the forum! Glad to have you onboard.
Unfortunately rvs are difficult to find right now. RVTrader.com doesn't have one for sale in the entire country. The closest new model to yours is a 22xb that has the corner bed, but the website shows that they are currently unavailable.
Other than scouring dealer websites and rv trader, you may have to wait or settle for another model.... if you can find one.
