@Deans25BRDS,
We have a long slide room the roof of which has proven to be a magnet for pine needles, hickory and walnuts, acorns and leaves. I've been using a collapsible ladder to get up there to clean it off before closing it which is a pain in the neck, especially when it's pouring out or there's a steep slope next to the camper.
We just bought a Lippert slide topper that will likely get installed in the next week..... along with a new awning fabric for the main awning and a set of JT's Strong Arm jack stabilizers and.........
If it takes my brother in law and I over an hour to install the slide topper it'll be because we're goofing off. It's pretty darn simple.
We paid $495 to Amazon for the 14' long topper and with Prime it was delivered for "free" about a week after we ordered it. I also ordered a roll of 1" butyl tape to put behind the top rail and brackets to water proof the screw holes.

And the butyl tape:

Here's a video of the installation:

I hope this helps you. I'll post back with the results when the topper is installed. Don't expect any in-progress pictures though because my BIL and I tend to move pretty quickly while working and we both suck at stopping to take pictures.
Best regards,
Lance
