The goal was to make the camper harder to see into (tint) and easier to see out of (new window).
From the factory our RV did not have tinted windows. The large windows on the slide made for great views but also had a bit of a fishbowl effect. Picking the tint percentage was tough. I ended up going with 20% ceramic tint. I am happy with the level of darkening from the outside without making the inside feel too dark. I spent more on higher quality ceramic tint for a few reasons. They are offer better heat rejection to keep the camper cooler, they are optically clearer, and it does not cause issues with electric signals like cellular and WiFi.
There are only two skinny windows on the front side of the camper. I wanted more viability. Both doors did not have a window so I installed a LCI ThinShade on the main door. This actually made a big difference. I took the door down off the hinges and measured several times before I cut the hole with a jig saw. The result was a nice factory look, move visibility out of the RV, and the tint of the ThinShade matched well with the rest of the RV.
