I have the 13,500 installed on my Starcraft 2008 14RT OFF-ROAD POPUP and it did require the braces under the ceiling.
I wish I would have installed the 9,500 BTU model now. We camp alot off the power grid and don't use the 13,500 all that much. The 9,500 model would have run just fine off our 2KW Honda EU2000i generator if I had thought about it at the time. Also would have been less weight on the POPUP roof. The 9,500 BTU A/C would work just fine for us as we are not all into the air conditioning anyway... Lots of shade in the woods... I have brought along my 8,000 BTU window unit from the house on some long trip planned outings and it runs like a champ on my 2KW generator.
My trailer has the electric motor and it raised effortlessly before adding the 13,500BTU A/C. It still raises ok but makes alot of grunting and pop noise now going up.
Now I want to add to some solar panels to the roof so I know I will be adding more weight to it. My plan here is to permanently mount one 120WATT panel to the rear of the roof between the A/C unit and the back with the solar panel across the roof. Then add some unistrut pieces across the roof on the front where I can place two more 120WATT Solar Panels in-line with the roof on each side of my Fantastic fan install. This will give me 360WATTS of Solar Panels. I plan on making these two front solar panels with a quick disconnect so I can add them after I raise the roof. These two panels will also be my two portable panels to setup on the ground if i need to follow the high sun.
Just some thoughts...
