I went with the 19.7. I did not want a slide, i know wierd. The table can be removed to fee up space, the lounge can be a bed, for the right size person. My kids will lay down on it to watch tv but thats about it. We do not do a lot of eating in the camper/at the table so 99% of the time it is put up giving us more walking space. I havent been in a 19.8 so i cant compare. We are a family of four and wanted a small camper and it works well for us.
