Can I use household caulk around RV windows?

I know you need a special caulk on many RV roofs, but I have to replace a window on the side of my Class C. Got the replacement window from the manufacturer, and I happen to have several tubes of household caulk (silicon base). Can I use them to do the job or do I need to get special RV caulk? Seems like everything that says RV on it costs twice as much as the regular stuff. Anyone with good advice on this??

Silicone is not recommended because it's made for things that don't move.

Might be fine, who knows but I would just use the Dicor made for rv caulk.

Personally I will not use any silicone caulk on my RV. You will never get anything to stick to it again even more silicone. 🙂
