MC20 fits below our camper van’s bed. When touring national parks, one needs to keep food away from bears. For other camping sites, we store our PT45 outside the van, giving our 2 dogs & us more floor space inside the van. Setpower tries to make something for everyone’s needs, and we benefit! Thank you, Setpower! Both our units are OUTSTANDING in ALL ways! Customer service is fast, friendly & competent! We are so glad we FOUND you or you found US!
