I just purchased a Reflection 315RLTS this summer so this is first time storing for the winter. We are seasonal campers so we store a lot of items inside of camper during winter because it will not be traveling on road. My question is, will it be safe to place items on top of the bed while the slide is closed? I've seen that sitting or sleeping on bed, sofa, seating, in a slide while closed can cause damage that will not be covered under warranty. Just curious because we used to store items on bed of old camper that was not on a slide and don't want to damage new one. Thanks in advance for advice.
