1990 elandan fuse box?

[Woodstove]

I'm desperately trying to find the chassis fuse block on my 1990 elandan 32rq. It's a Chevy p30 chassis with the 454. I've been at it for a couple of days, any help would be apreciated

Compartment under the radio maybe?
Winnebago was notorious for hiding them under the dash...
