If you're looking for a manual or instructions, I suggest going to the Forest River site.
You stated "new" but that could be 2018, 2019, or now even a 2020 model.
The only "Wildwood X-lite" I could find on the F River site was for a travel trailer, but there are some "Wildwood" Fifth Wheels as well...
In any case, I would start here - the site/manuals are pretty easy to navigate.
Please let me know if this helps! THANKS
