Infant in a travel trailer

We are expecting our first baby and have started to think about sleeping arrangements for our travel trailer next summer. We don't have a slide out so floor space is limited and we don't want to put a pack n play on the table because we use it frequently and don't want to take it down/up for every nap and bedtime. Does anyone know of a good bassinet that would fit on the bottom bunk, shown below, for 0-6 months? We plan to upgrade to a camper with a slide out for the following summer so we have floor space for a pack n play.
