Can you say why you think the volunteer FF was a *huge* time commitment? I am a member of a volunteer fire brigade (have never been called out, thankfully). I put in about 12 hours a year. The town I grew up in had only 4 full time firefighters, and 200 volunteers. My uncles were both volunteers. One spent about 10 hours a year actually doing anything fire-related, the other only went to the barbecues and organized their float in the town parade.
I say this because I have a good friend who is chief of a fire academy and a colleague who is the chief of the only other fire academy in Southern California. The second group trains "volunteers" for wildfire certification (it costs about $500 to attend and they only take 20 people per year - it's an investment of about 80 hours - I am watching friends on the waitlist for that training for more than 4 years).
In other words, I'd say spending money for a real wildland fire training certificate (which is gained mostly by people who are seeking full time fire employment but are currently volunteers) is evidence of a moderate investment of time. 80 hours is two weeks of work. I've spent that much time training (per year) in forensics until I got old enough to semi-retire. My younger colleagues easily do that much - on their own time - just in hopes of publishing or getting tenure.
And I'll finish by saying that most of the people I know who are volunteer FF (or SARS) spend about 12-30 hours a week - documented - but we don't have that for Barry at all. Who has he searched for? Where is the documentation of any time spent other than training in 2016 and 2018 (summer volunteer training - we don't know how many hours. Was it like my training? Was it like the training of my colleagues who are now one level higher than I am? My initial training was 20 hours - I don't consider that major at all).
I spent way more time on WS (I realize I"m about a decade older than Barry, but still). I've looked into the volunteer fire training for Chaffee County and also into the various trainings at the Chaffee County"wildland" fire camp - and it looks like a fun weekend with barbecues, friendship, and learning to use a chain saw or other equipment (we had chain saws at my training too - and hoses, and search and rescue). They don't even have a rappel station or a wildland fire structure to train with. They do have a wood chipper.
Scroll down on this document for their curriculum:

I've done all of that curriculum in my training (there are job related reasons why I did it, btw - but I didn't get paid to do it). I was not especially good at it - but neither were a lot of other people. I've actually done extra training in medical and community relations, as well as communications (I was named the Communications Officer for our practice runs). We didn't do river training, as there are no rivers in SoCal at this point in time, but we did do Earthquakes and Bombs.
From what I can tell, to get tthrough Chaffee volunteer FF, you need to put in about 4 hours a week (we put in 8 hours a week in my program, for 6 weeks) for 13 weeks. We did our oral interviews in advance and had to do CPR separately. I will admit I only watched during vehicle extraction - but that was true of nearly all of us.
My point is that being a volunteer FF is a wonderful way to serve one's community and my certificate is proudly displayed on my wall. I am envious of those who went on to further levels of training, but still, here I am, able to show my credential to a real, certified, salaried FF if we have a catastrophic event here in my area (and we could - the Thomas Fire just missed where I live by about a mile and I did get to volunteer for communications and traffic management - my vest and my official stuff is in my car right now).
We didn't get a barbecue as a graduation - but a lot of people did go out afterwards for food and drinks (I didn't, it wasn't a social thing for me). It's a social thing in my home town, not so much in my work town.
I only wish I'd done level 2, to learn to belay (but to do that, I had to volunteer to rappel...I wonder if Barry ever rappelled anything - I would wager that he hasn't; the equipment needed would be provided by the volunteer - I have it - it's not cheap).
