do you have the wiper pivots with the squirt nozzle built in or will you use a different squirt nozzle that gets mounted on the wiper arm or hood etc? I ask because the original nozzle that came with the task force trucks and is part of the pivot has the hose connection inside the truck cab if i remember correctly. that way your washer bottle could be placed in the cab out of sight.
some vehicles mount the washer reservoir behind an inner fender with a simple fill spout sticking through the inner fender under the hood. my wife's audi is like that. you could fab a reswervoir from abs or pvc plumbing pipe and have it mount behind the inner fender and nobody would see it unless the truck were on a hoist, the pipe would take a rock thrown from a tire etc without a problem I would think, the fill could be a small cap near the rad support
cat makes a decent looking nozzle that attaches to the wiper arm if that interests you

or you could do what ogre does and not have wipers, just use rainx.
I'm not there yet but will use wipers but I have the original pivots with built in nozzles. my washer reservoir will likely be under the hood if I can find room. under my hood is packed with stuff. not a show truck so not worried about that. lol.
LG, I like your functional but clean and tidy looking engine bay.
