It had a screen...but it was a sliding screen door from Phillips. Not a traditional one. $3200 is a ridiculous price. That has to be a mis-print. You can find an RV replacement door online for under $500.
I'd recommend checking out Elkhart RV surplus or something like that. The door simple screws in from the front. The key is finding the right size that will fit your rough opening without needing to modify the aluminum RV frame (maybe that's what they were including in the price).
Take the door out, get some dimensions of the R.O.
