i have the full cab. i had the glass honda windshield. comparing that to a vikings fold down window from plexiglass, i would go glass and never ever look back. the window is made in america, steel frame. and the optical clarity of the glass is outstanding. you do get dust in the cab, and lots of it. i would reccomend getting a half windshield for summer, and the glass for late fall or winter once the rain starts.
i rolled mine and shattered the glass, the new quote for a auto grade glass from a local glass shop cut to fit is 150 without labor to install.
leave the plexiglass alone and just buy glass if your going full. ive had both, and i only like one.
also, you can use the rain X anti fog stuff on the inside of glass, i think it will eat the plexiglass though im too scared to try
