New Onan 4000 in Argosy 20 MH

[JWTyson]

Hello!

I have a 1977 Argosy 20 that I need to replace the generator in. Currently it has an Onan BFA 4.0 and I'm wondering if the space it sits in will be large enough to house a new Onan 4000. I can't seem to find the sizing specs of the current 4.0 that's in there.

Thanks for any input.

Thanks for any input.

Smokestak.com (an antique engines forum) lists these dimensions for the BFA 4.0:

Overall length 30.5"
Overall width 18.5"
Overall hight 19"

I don't know this from personal experience, though, so take it for what it's worth.
