Opinions on Twin Beds vs Fold Down Couch

I like the twin beds. They double as sofas. We use a 1/2" pad covered in a twin sheet. We roll it up with the sheet on it if we need a sofa. Most of the time we just eat from the front seats during heavy rain and outside at a picnic table in good weather or a light rain while using a portable cover. The outdoors is much nicer than staying cooped up in a B all the time. Bs are great for sleeping comfortably without heat or mosquitoes. The rest of the time is usually outside.
