No slide.
They're worrisome. I was always crossing my finger whenever I pressed the button to bring it in or out. The slide on the camper I bought last year went bad and I went from Pennsylvania to Indiana without using it.
At the manufacture's rally last September, they looked at it and sent me to the factory for 2 days. One campground later, pushing IN put it out, and OUT brought it in. The connection arched. One campground after that, the slide went bad again.
I would only go back to having a slide if I become a snowbird. Six months in two places. Moving often is alot of wear and tear on slides, plus extra worry for you if a "what if" scenario happens.
Some slides do have a manual way to deploy them or bring them in (a rod used from the outside or access through a panel on the inside on the slide motor itself that a still can be used), but you'd still need help.
Having extra room is a plus but it doesn't outweigh the headaches if something goes wrong. You could wait months to get into a dealer and mobile techs aren't equipped to actually fix them (my opinion) but they can at least help get it in if needed.
Unless you're planning on spending more time in the camper, instead of being outside, sightseeing, enjoying weather, etc, you may only be inside to make dinner and sleep.
I find I'm not bumping into anything, and the dog is only in the way if I open the refrigerator cuz he wants cheese.
Something else to think about... sounds like you're looking for a class C. I was also when I first started looking. Not finding a Floorplan that I liked was a problem, but what made me settle on a trailer is:
No insurance for 2 vehicles
No maitenance (oil changes etc) on 2 vehicles
Having a truck that can pretty much go anywhere
Just somethings to think about based on my
personal experience.
