Oops ??

First, post a picture so can all give you better options.
Second, it seems new things are always destined to get their first scratch or damage. So yours is done now. Lets just find the best way to fix it.
Third, I suggest a hardening epoxy applied smoothly. Then place one of those decals on it that looks like a bullet hole. It will give you something to chat about at fuel stations and camps. Then just enjoy your new camper!

You could also fill the hole and put a reflector on the outside of the 5th wheel with caulk around it.

Yes, I'm sorry to tell you that it IS a total loss. Give me your address and I'll come take it off your hands. ;)

Is it someplace that you could use the exterior hole to mount something else?
Maybe a light?

Before you drive yourself crazy, ...take a deep breath... EVERYTHING is fixable....( ALMOST )

1- does it go ALL THE WAY from inside to outside?
2- what size hole?

IF the outside hole is where you need it, squeeze sealant into the hole, place the mount on the exterior wall, dab some sealant onto the screw and tighten... that SHOULD take care of the exterior hole..
And for the inside...depending on where it is -
* seal it... AND
*hang a picture....
or
*place a piece of trim over it
or
*get a piece of wallpaper that matches, cut out a small diameter piece just large enough to cover the hole..
0r
*hang a coat hanger

A small diameter vacuum line or a piece of shrink wrap just shorter than the bit will prevent that from happening again.
My lesson involved a new 1972 Buick Estate wagon and a roof rack install. I've never forgotten that lesson. The drill bit ate the entire headliner before I could get my finger off the trigger of the drill.

Put a little sealer in it and stick on an american flag decal.

A friend put a hole in the wall of his brand spanking new trailer backing it into his driveway for the first time.He backed into a sturdy tree branch. After much crying and pondering on how to fix it, he bought an outside lite, fastened it to the side of the trailer and it looks like it belongs there. So you can hide these mishaps in various ways.

Look at the bright side, you won't make that mistake again. ;)

Hey, the hole is there, use it for the mount. Get a correct size stainless steel carriage bolt (with the smoooth, rounded head) at Home Depot. Put it through from the outside with a little dab of Dicor non-leveling sealer on it and paint the head to match the RV. Just do not overtighten it. RV walls are pretty soft compared to the ability of something with threads to crush them. No one will even realize it was a mistake!
