I removed, (and sold
,) my factory installed Fiamma awning. I didn't care for it at all and rarely used it, (as in 4 times in 5 years.) I also didn't like the way it wasn't properly sealed to the trailer to prevent water leakage from running down the side of the trailer to where it hits the belly band and splashes all over everything "supposedly protected" under the awning. I personally found it to be relatively useless for deploying in the PNW climate, where it is more rainy than sunny, mainly because of the extremely ill-designed mounting brackets. (The whole mounting methodology seemed to be a total afterthought. Gee, let's mount an awning designed to be mounted tightly against a vertical "stick built" trailer side wall, and try to jerry rig it to "sorta work" on a rounded top of a trailer that it doesn't fit on. Great piece of practical engineering there!) Anyway, enough rant...
I installed a Keder rail (about 7 ft.) on the side of my trailer and it will hold either a slide-in "bag awning" or a conventional "rope and pole" awning. It also fits tightly to the side of the trailer and doesn't leak.
I drilled the rail on 1 foot centers and mounted and attached it with 1/4" X 20 stainless steel machine screws and and nylock nuts and washers inside. All mounting screws are hidden inside the upper cabinetry in the trailer.
I also much prefer the cleaner lines of the trailer's overall appearance without that ugly awning, but that's just me.
