are you insured
if deductible is around 500 I would put in a claim for window and the cracked fiberglass
check your homeowners insurance it should cover your trailer while parked at house?
check the stickers some more and see if you can find the manufacturer of the window.
or if you can't locate exact window
TAKE OUT the whole window and measure the cut out dimensions and find a window that will fit in the hole
TINT can be added before you install it.
take new window and the old one to a local tint shop
you could try a local glass / window repair company see if they can duplicate glass shape and tint
use local automotive body shop to repair the fiberglass and color match the gelcoat
DIY ... get a fiberglass repair kit using glass cloth
Poly resin + Bondo will smooth it.
OR using epoxy resin .... Thicken the epoxy instead of using Bondo.
Bondo doesn't stick well to epoxy resins
