Non-Venturi Generator Exhaust Extender Ideas

Folks,

I will be heading out on a trip to spring training in Florida here in several weeks.

I will be using my genset, and want to be able to safely use it overnight if necessary. I have a few concerns about the exhausting of genset. It dumps out right below my full wall slide.

I want to look at a way to extend it out past the slide, and don't think a venturi styled set-up will work since I would have to clear the extended slide before going up.

I have heard about some folks using a alternative such as an aluminum flexible conduit. If you have used this, or seen this or have ideas about this or anything which may work to get this exhaust out from under my coach, I would love to hear about it. Also wondering about how it attaches to the muffler, and how you would keep it from recoiling, etc.

Thanks for you insight, and hopefully I can get this rectified before I leave next month.
