I liked the slide on my previous camper. I traded it out for my current one only because it wasn't a good fit for the camping I like to do. I happened to fall in love with a camper with no slide this time around.
Just... realize that Murphy's Law is a real thing. When my slide did break, it was really nice to have no issues using the bed, bathroom, furnace, and making a sandwich for dinner while on the way home. Make sure the trailer is useable - even though it's cramped - with with slide in. There are lots of floor plans that work.
