I have camped in cold weather in both a travel trailer and in a Class C motor home. We now have a Class A motor home.I have driven in snow and ice in a with a truck and trailer which is very difficult and in a motor home. With the truck and trailer the truck had studded snow tires and I also had 4 tire chains. The truck had a G80 mechanical locking differential and 4 wheel drive. With the motor home it was equipped with a Tru Trac limited slip differential ABS and snow tires. The Class A motor home has Eaton NoSpin locking differential and ABS and tire chains for all four rear tires. The major challenge with a motor home is most of them are configured with an open rear differential which essentially turns them into a one wheel drive vehicle. This coupled with regular tires and no traction control you are very limited in where you can go. It is possible with tire chains but the road must be sanded there cannot be too much snow on the road and the grade cannot be too steep. Putting tire chains onto 22.5" tires on the side of the road is no fun either. The trick is to go slow and take your time. Don't go down any major grades that are not serviced i.e. sanded and plowed. By all means don't go down steep down grades on compact ice and snow without tire chains. We four season camp so we can get caught in ice and snow. We have always gotten through. We carry the right equipment and have made specific factory approved modifications to the coach to be safe. On the other topic most Class A diesel motorhomes are equipped for cold weather use with heated basements and enclosed plumbing and dual pane windows. Some Class A gas motorhomes are also equipped similarly. We added a mechanical dehumidifier to keep the motor home from having condensation problems. We just connected to water just long enough to refill our freshwater tank. The sewer hose was connected only long enough dump the black and gray tanks.
