Welcome to the forum its a great place to get your questions answered. condensation is usually caused by improper air flow especially in winter camping with that said it can happen anytime. I think before I started tearing things apart I would dry up the areas and make sure you have good air exchange when the rig is setup. On my rig I have found I have to keep the from window cracked and the bedroom vent on low to stop condensation during cold times.
