If you looked at the layout on line and are happy with that, after reading ScottG's post with the exact same one, if it was me I would go for it.
We are in a similar boat, but all ready committed. Our 2017 trailer was totaled with the salt water storm surge from Irma. We wanted to replace it with one slightly bigger and did a walk through of one that was a 2017 but already sold.
They told us the new model (2018) would be the exact same layout but with different interior colors. We looked at them on line and decided to go ahead and gamble. It should be delivered the end of this month and we are keeping our fingers crossed.
