Year hi-lo started using fiber glass fronts ?

[FHILO]

Back again, i'm confused because theres a hi-lo on mash rv that says its a 78 but it has a fiber glass front & the 78's Ive seen don't have fiber glass fronts & its windows are different etc nothing looks the same as the ones Ive been seeing . there is also a supposed 74 too. Same thing .Fiber glass front but looks nothing like the ones Ive seen . By the By i own a 78 and no fiberglass . so what are these hi-lo's ? Are their owners wrong? id down load the pics i have so you guys can compare but haven't gotten that figured out yet. hope someone can clear this up for me. they swear they have the right date for their hi-lo's but so do i. At least my paper work all says 1978

Fiberglass front

Your right there wrong .i saw the 74 wrote the people no reply. I also have a 78. I dont know what year it started but the two you saw are not the right years.

My first one was a 1980 21 ft, and it had the fiberglass front and rear..that narrows it down some..
