Replying to Swing set slide as a drop in?

so im making a setup for the fall and the winter, i have my rail built, but the only problem is that my yard is flat as fuck. then i has this idea that i would use my swing set slide as a drop, to save me some money and a shit load of work. It tried it out and it worked pretty clean, i was wondering f anyone has used something like this for a drop in? 

thanks
