FG Trailer and insulation?

Adding room for insulation that has enough volume to be effective within a fiberglass shell generally means creating some space for the insulation by adding wood framing inside of the shell. The weight of that wood framing quickly adds up with all of the pieces that are needed plus you also have the weight of the materials to create the inside wall surface which has to cover and protect the insulation.

Therefore as far as I know there are no light weight true 4 season molded fiberglass shells. The materials used to make them 4 season make them the opposite of light weight.
:if you use the knew special in a bottle Spray Foams one does not need to put wood studs in place to hold it there as this stuff has it's own glue which holds it in place and also is very light.
I have used this for boats, Cabins, houses, almost any application where you need insulation.
One thing you never want to get this stuff on your clothing, skin, hair as once there it is there forever, so make sure you wear clothing you do not care about also when applying make sure you have a fresh air mask so you can breath as this stuff goes on quite hot which in turn makes the air your breathing hot.

I wouldn't think of using anything but the built in propane heater. Millions of RVs use them and they have been proven to be safe and economical. The furnace in Scamp 13' will drive you out if want it hot, no matter the outside temperature is.
I keep it on at night with the thermostat set at between 45° and 50°F.
In a small volume like my Scamp I need to keep the roof vent open a bit and the small window over the stove open a bit no matter the weather to keep fresh air inside and O up enough to breath and the O2 down.

Are there tiny woodstoves made for trailers and RVs or does a person have to just get or make the smallest one they can find and get creative with how to put it in, to avoid carbon monoxide poisoning, leaks in roof, etc?
Also interested in solar and wind.

Thanks -


I have much experience in using small wood stoves in ice shacks and hunting cabins. You want to rely on wood over propane? Besides oodles of reasons revolving around safety, wood stoves are either way too hot, too cold, and must be fed every hour or two. So good luck sleeping and being consistently comfortable.

Sorry, with fiberglass campers a wood stove would be beyond crazy.
