Thanks for the reply. Guess I'm glad there not built like houses. My duramax 2500 would probably not get very far down the road. I guess a good dehumidifier is in order.
Thanks

Or you could do what a lot of us do and use those wheels to move to areas when 0° is unheard of in the winter. Even 32°F is extreme for us in the winter.

I think I ask the wrong question. I'm trying to find out the difference between four season and a 0 degree rating. It sounds like neither one will solve the condensation problem. However, there may still be an important difference I'm not aware of. I've googled it but could not find an answer and am hoping someone can explain it to me.

Remember those 'labels' are all manufacturer advertising gimmicks. There is no definition of what makes a 4 season rig or what determines that a rig is marketed as '0 degree' sustaining rig. And really there is no rig that is made to be used in 0° weather for extended times. You're going to need to do a lot of work to help insulate that rig so that you can live comfortably all winter long. BTW - what is the average winter humidity in the area you are going to be staying. In a lot of Colorado the humidity is very low (can't make good snowballs) and thus just making sure you have good ventilation including fresh dry air coming in will take care of any moisture generated by living.

No matter the rig if you heat with propane (LPG) you're going to get condensation as propane has a lot of moisture in it. We wintered in Deer Park, WA several years ago where the temp would get into the -0 and learned to use electric space heaters to prevent condensation. Heat with electric and you'll reduce your condensation problem by roughly 80%.

Thanks, base board heaters would be easy to install. For those wondering our grandkids live in the Rockies and are avid skiers. Gotta spend time with my snow angles while they still have time for us. I had not given consideration to the very low humidity in the Rockies. Thanks for the replys. Wendell111

If you are getting moisture from your propane furnace you need to have it checked out immediately. When propane is burned the byproducts are CO2, CO, and water. And that is the reason that they are EXHAUSTED to the outside. The air that is heated is heated in a heat exchanger and isn't involved in the combustion process. Same for the water heater - the heating is done so the exhaust is outside of the rig. The reason you might think you are getting condensation from the furnace is that when it is on, the fan moves air completely around the rig, carrying moisture from human activities like breathing, bathing, doing the dishes, etc., to every corner of the rig where it collides with a cold surface and condenses.

Now the burner on the stove, that will give off some CO2, CO, and water - - which is why you want to at least crack a window while cooking so you can move the byproducts out and bring fresh air in.

The big thing is a lot of damage will happen wher you can't see it at first.......INSIDE THE WALLS. Moisture continuing to build then the FRP(if that's what yours has) will start to delaminate. Some of the inner structure on cheaper/lighter units are mosty wood and will rot and delaminate. Some of the larger/heavier units are steel tubing structure which will start to rust and cause delamination. Most will say how they skirt in the bottom perimeter with styro-foam to keep warm in colder climate.....
But you are still trying to heat this huge "Thin Walled Box" and with cold outside of the box and heat inside the box.........You will be making nothing but Gallons of condensation.

I think 4 seasons in Alaska or Minnesota and 4 seasons in South Louisiana or Florida are two different things.

It's all subjective. Like the song says, I plan on moving where the weather suits my clothes. I'd rather spend my money on fuel for moving to more pleasant climes where I can go outside in comfort, than on fuel for heating where I must stay bundled up inside all the time. It's why we have wheels, IMHO.
