welcome to FRF!
just so you know, Allegro Bay is not a Forest River brand.
so you should be able to get help with general RV things but not with things specific to your make/model of RV.
i would think that there's a Tiffin owner's website somewhere. they're pretty loyal owners of their Tiffin products.
