Got this idea from the Thor video of all places (I posted the video in this thread http://www.thorforums.com/forums/f17...ide-10287.html
-- its the Thor walkthrough of the Vegas 25.6 video where its mentioned ).
If you don't want to watch they had mentioned setting up a projector inside the RV and using the front drop-down shade as the screen (one of those 'doh! I can't believe I didn't think of doing that moments!).
I've used a projector in our back yard a few times. The first time projecting onto a screen made out of painters drop cloth held up with PVC pipe--until the PVC pipe collapsed LOL. The next few times I've hung the drop cloth against the side of the house and projected from the neighbors yard (at the time they had a big fire pit so they lit a fire and both our families watched the movie).
RV'ing we did project once on the side of someone's RV (and watched RV no less LOL).
Of course now I want to try the inside front shade trick...LOL
