The situation is resolved, at least for the moment. The storage yard where we keep the RV also sells trailers and pick-up campers. Not Forest River, so I won't name any names. Anyway, I had seen the men doing work on various units, and so I asked if they did minor work on customer units, or if they just did dealer-prep.
I grabbed the co-owner and we went to the yard to have a talk. We were both having second thoughts about the dealer's shop, especially after reading several reviews about them.
Turns out they're quite happy to install vent lids and covers. Parts will be ordered on Monday and installed within the next couple of weeks. They'll call and let us know when to come and unlock the motor home, and the work should take only one day. Plus, we don't have to drive thirty miles in San Francisco Bay area traffic!
We called the dealer shop to cancel. They said, "Just give us a call to re-schedule." Won't happen, at least this time.
To grumpy 0374, I appreciate the offer, and probably would take you up on it. Dinner and a beer would be a bargain; I'd give you a twelve-pack or a case as well! I would love to learn to do some of these repairs and modifications we have in mind, but just don't have the experience or skills to do it. I did replace our WFCO converter with a Progressive Dynamics one a couple of weeks ago, and it was pretty straightforward. The converter runs a bit warmer than I prefer, so I'm putting a temperature-controlled fan in the compartment wall to pull the hot air out.
Anyway, I ramble. Thanks, everyone!
