It is amazing how much space a slide provides. If you really need space inside then you will need a slide.
I had one for a few years about 10 years ago. I did have trouble with mine. Luckily I could hand crank mine in or out so I was never stuck anywhere. I would seriously advise you to look into a slide out awning to protect the top of you slide. I was out in the late fall, fishing in Montana when it snowed a couple of inches one night. The next day the sun came out and things warmed a bit. The second night it snowed another inch followed by another nice day and warmer temperatures. When it came time to head home, I had a nice block of ice on top of the slide. It wouldn't move in and I couldn't get on to of the trailer. It was a real challenge but we managed to McGiver a solution. I also had water leak into the trailer when bringing the slide in during rain storms. It was a challenge.
If I were buying a trailer with a slide these days, I would ask about these kinds of issues. I am sure they are better than the one I had.
