Hey all, so we used a Nebula capsule projector mounted via a SMALLRIG clamp on one of the gas struts for our pop top roof. We kept the projector mounted all the time we were camping and used it as a speaker during the day.
The screen is just an A1 sized piece of foam board which is hung via Velcro straps to the inside the pop top. It stores away inside the roof when it’s down.

Hope this helps! The projector seems to have shot up in price since we got it though unfortunately.
