Hello, just curious .we're looking at purchasing a new Viking 2107. The underside of the bunk ends are unfinished plywood (not painted or sealed). Is that normal? I was also looking at some Jayco models, but didn't remember to look on the underside of the beds. I know they'll be pushed in when the tent trailer is folded-down and stored, but shouldn't they also be protected from the elements when they're pulled out and used at the campsite?
