slide topper 2020 Alpine

[johnnyRV]

Are the gutters installed on my 2020 Alpine 3320 MK ready for slide topper ro will I have to remove and install the topper rail?

Just look at the gutter, does it have an integrated awning rail? If not then you install a rail underneath the gutter.

There are two types of aluminum extrusion used by Keystone and I've found no "concrete assurance" of which is installed on specific trailers. I've seen "same brand same year same model" with either of these, with trailers sitting side by side on the dealer's lot.

So, the only way to know what you have is to look at the drip rail above your slides and see what's installed. If it is a "drip rail with an awning slot" then that is all you need. It will look like the first photo. On the other hand, if it is "only a drip rail with no awning slot" then you'll need to either install an awning rail under the existing molding or remove the existing molding and install a new one with an awning rail. The drip rail without awning slot looks like the second photo.

Yes - your Alpine came factory with slide out awning rear rails premounted... ready to install a slide topper..

Before you install the slide toppers remove and replace the wiper seals on at least the TOP side of each one... The hydraulic slides all use the clip on seal and the schwintek in wall electric is another style...

** After 4 years I can attest those top wiper seals are not doing their job as the edges of the seal are by now curled up..

Changing out a top wiper seal after you install the slide topper is a pain... 10 minute job right now... much more difficult with the slide topper installed..
