Beds are pretty much a personal decision. I would go spend some time in these units at a dealership, lay down on each of the bed types and see how they "fit" you. Also, consider the floor plan as to which meets your needs the best.
By the way, my son has owned 2 mini lites and both have been totally trouble free since he bought them. He owned each trailer for several years and will probably buy Rockwood again when he needs something else. You will be pleased with any Forest River product.
