Beginner question; Trouble thickening complex shapes

Hello Everyone,
I was hoping to get some more experienced eyes on my project.
I'm pretty new to Onshape and CAD design in general, and am still familliarising myself with all the features, so my project may be a bit ambitious. What I'm trying to design is an airbox for a motorcycle, and I'm stuck trying to model what could be described as a funnel with two spouts at different angles. It kind of looks like boxer briefs, so I call it the trunk.
I pulled reference surfaces off a 3d scan of the motorcycle, then ballparked where my design is supposed to sit, doodled some ideas, and then sort of reverse engineered my work with clearer intents and driving dimensions.
Here is my model:

find the trunk under version "Showcase Design intent"
I run in to trouble trying to go from surface to solid. Only the two outer quarters will thicken, the middle where the two funnels merge will not. I've spent many hours reading and watching videos to learn more about various design strategies, and spent even more time trying to work around my problem with the "enclose" tool, only to arrive at a good looking but still hollow "trunk" with what I can only estimate is a hopelessly convoluted workflow. (version "Fully enclosed but can't make a solid")
I'd be very grateful if you could take the time to have a look and give me some pointers, either directly to the problems in my workflow, or towards resources to help me improve and find a solution myself.
Cheers!

You could just use a fill surface 3 times and get it solid.
Areas like this will always be problematic for shell/thicken as the geometry kinda overlaps/kinks on itself
