Is it possible to fill the walls with insulation?
Like on a regular home, by drilling 1/4 inch or less diameter holes spaced how ever far apart and using the atypical home insulation machine?

Why do you think they aren't already insulated?

Because its a 91 and everything settles and even at "only" 40 or so here in Oklahoma, it has been a complete freezer in here despite the other ways I have sealed and insulated.

Short answer...Doubtfull....And how would you re-seal those holes in either the fiberglass outside walls or even the inside walls without having a major convoluted mess and still look like an ill designed lowest bidder government cover up.
I suggest that you bite the bullet and replace your coach with one that has an "arctic package " with dual pane windows if possible.

Thermal Imaging (FLIR)
Might be worth it to hire it done. See where your heat is going. Heat travels to cold.

You could use an IR gun to determine where problems exist. Haven't heard of anyone doing that for the past 14 years that I've been on three RV forums so I don't think it is a worthwhile endeavor. If it worked everyone would be doing it, especially the people who live in cold areas.

Hello
We put Reflectix in our closets, inside our cupboards, and under sinks on the outside walls. Don't know if it would help with the cold but it sure has kept those areas from getting hot when shut up. It's the silver bubblewrap that you see in people's windshields to keep the heat of the sun out.
Check out YouTube for videos on how people have insulated. You may have already done that but the walls of an RV are only so think and not sure they could help in cold climates anyway.
We had a window out one time and were able to see inside and the wall had the stiff Styrofoam board insulation inside the wall. It's not very thick though.
Good luck, Lynne

Do a couple of test drills with a 1/8" or maybe smaller drill bit and see what you get in the shavings. Should be easy to pick out spun fiberglass from styrofoam and if there's a empty void due to settling. Considering the model year of the OP's coach it could have spun fiberglass. Nondestructive testing with an IR camera might be a better option if the warm windows, which can be the largest source of heat loss, don't overpower the sidewall temperatures.
When temps drop I'll start covering windows with reflective insulation and pull the slides in for a better seal and smaller exposed surface area. Made a significant improvement regarding furnace cycle time. The windshield is my biggest source of heat lose.

I think most if not all have solid insulation panels behind the walls. It gives stiffness to the outside walls as well as something to glue the paneling to on
the inside. Check out similar models in the forum that have redone their interior and you can see the panels laid in between the studs. They are only an inch of so thick so not a lot of insulation value.

Yeah At BEST the R value is 6??? But in mine it just struck me wheel wells and bays are metal no insulation at all. We are expecting a cold front tonight. It might be a good test to plug in a 1500 watt heater and move the wireless thermostat in it.
Thanks for this thread.

You would have to check each manufacturer and each model to confirm. Newmar lists batten insulation in the current brochure for both the roof and walls.

If your coach used batt insulation as opposed to solid block foam, then yes you could in theory spray in additional foam. However, it is unlikely that the manufacturer used drywall on the interior, meaning that filling the wall with expanding foam could very easily bulge the very thin luan or whatever material was used on the walls, or failing that it could blow out at seams/joints. Worst case it could also blow out to the exterior of your coach around the windows or seams in the skin.
Seems like a big risk. If you want to reinsulate, you are talking about removing interior wall panels.
