I’m planning to camp in California this winter and some locations may have overnight temps in the 20’s though daytimes may be up in 50’s and 60’s. My Reflection has ducted heat to tanks and I can keep a faucet cracked to decrease frozen pipe possibilities. I wonder if temporary skirting and subtle heat under the trailer has been tried.(light bulb under the hood worked for my Jalopy back in the day) I’m camping in one place for a month+ at a time
