Just be aware that fiberglass work for boats is different than fiberglass work for airplanes. Weight is important! I’ve done both, and there is a totally different mindset for each. I’d find an experienced airplane fiberglass guy to help you learn the fundamentals. Fortunately, there is a great RV building community in the Twin Cities! I’d suggest posting a new thread with a title something like “Looking for some Fiberglass help in the Twin Cities area” and see if you can’t smoke someone out.
What you’ve got doesn’t look bad - you just need someone that has been there to show you the ropes.
