I put tinted plexiglass in the front and rear windows
of a S-13. I think it improved the looks, but that's just me. I have seen trailers with film installed on the windows and it was a mess, don't go that route.
During the day you can't see inside the trailer if just walking by. Not so at night with the inside lights
are on. If you like to open your curtains while driving to see through the trailer you loose that option. On the inside looking out during the day it's just like having sunglasses on.
I lucked out the local plexiglass shop had enough tented arcrylic O/H to get two windows out of. If not I would have had to buy a whole sheet of plexiglass which you get 4 windows out of one sheet. Also Scamp
mostly used 3/16" arcrylic for their front and rear windows. Not a common size to be found in the big box stores so tinted or not it may have to be special ordered.
I use the Scamp beading and it does ok with the elephant hide. If it leaks
a glass shop can inject sealant behind the seal to stop any leaks
I am working on a 77 Scamp that has the thicker arcrylic like yours. but most trailers have the .177 arcrylic in the front and rear windows.
