I have a 2018 silver back 37rl. Is it possible to increase the insulation in the underbelly? It is currently 30 or under and the floor gets very cold which I think contributes to the rv cooling fast. Any other insulation tips would be appreciated. My neighbor has wood trim covering the metal window frame on the inside. I also think that might make a difference. Thank you for the help.

You could remove the cloroplast underbelly and then remove the insulation and replace with any manner of things for additional insulation. I'd doubt it'd have much effect, but maybe it would.

When it was 18 at night here last month, our furnace kept the whole thing relatively warm. But I'm sure more insulation wouldn't hurt. I guess it depends on the grief to earnings ratio! How often do you camp in cold weather? Enough to justify all that work and expense? If so, go for it. I'd like to see pics of what you do, if you do it.

THICK Wool rugs will be a big help.

Very hard to get ALL the cold entry points under most coaches.

2 layers of rug are even better than one,

Thermo wrapping the glass area , inside and outside is a big help , as are "warm shades" , that use magnetic stripes to help seal.

Spray foam the whole underbelly and hope you never have to take it down is what we did.

We had a 2002 Vanguard insulated with sprayfoam but holy c..p if you ever need to access anything or have a water leak somewhere.
I would not do it again and instead open the underbelly one panel at a time and fill it with bat insulation. If you have slide rails in the underbelly make sure you encase them in plastic pipe so no insulation get jammed in the gears. Make sure you seal access points for electrical, propane and others.
