Hi PiddleandFutz!
Yes, I agree with you, the right hybrid is sort of a multi tool… sorta like a Mac26X and Mac26M are in boating.
They can both do a lot of things…and do them reasonably well.
Several years ago I saw read an article where someone rigged a 2500 Watt portable generator on the back of a clapped out early model EV that when new had about a 100 mile charge range or something like that. They drove it across the country… I believe from coast to coast or along those lines…
I don’t doubt that given the truck genre that this may have already occurred… a couple of times…
A coworker/friend, back in 2016 before I retired bought a Honda Hybrid sedan.
He is still driving that same vehicle with apparently the same battery pack I was recently told.
If true, That’s a long time for the battery pack, but I wouldn’t put it past him to see just how long he can make it last just to know.
Apparently he has only had the regularly scheduled maintenance done without any issues inbetween.
Last I heard he was well into the mid 100K mileage.
His daily commute was about 20 miles and he primarily charged it at work at the company’s free charging station. Seldom at home.
I contemplated getting one but my commutes averaged about 120 miles a day…. The battery ranges back then weren’t really up to that and back then the battery change-outs were expected every 3-to-5 years… they weren’t cheap either!
So it really wasn’t a good fix for my application at that time.
So while a hybrid has its limitations I believe it still has some really great advantages.
Back in the 80’s I had a peppy little VW Rabbit that was real fun to drive but back then I was in Texas and it was a long way between anywhere with a lot of lonesome space in-between. Not many 24 hr gas stations either back then in the lonesome sections.
I rigged up an auxiliary fuel tank in the spare tire well that expanded the fuel capacity by about 10 gallons which added a bit more than 50% more mileage range. It was covered by a 10 gage sealing cover plate and connected to the existing tank for fill and use.
I loved that when I filled up both tanks some of the gas station attendants wouldn’t believe the amount of fuel that Rabbit could swallow!
While legal in Texas it wasn’t going to be legal in California ( Note 1 ) (where I was moving to start the next phase of my adventures) so I easily removed it before moving there. (Professionally and personally Moving out of Texas after 12 years to California was one of the better things I’ve done! I never looked back. While we eventually moved East 20+ years later to New Hampshire and enjoyed the New England region there was a whole lot to like about the San Francisco Bay Area!… No snow shoveling was one of them!

)
It was fun while it lasted…. I mention this as depending upon your current state DMV regulations you might want to consider the addition of an auxiliary fuel tank for your Volvo. Nowadays there is probably already a DOT approved one available. ( Note 2 ) Might be worth looking into…
Best Regards,

Note1: It's important to be aware that auxiliary fuel tanks are subject to California's anti-tampering laws, meaning that installation of aftermarket auxiliary fuel tanks on emission-controlled vehicles is prohibited unless they have been certified by the California Air Resources Board… a DIY tank obviously didn’t necessarily meet those requirements nor was it worth it to me to try and get it certified.
Note 2: Per Volvo… Volvo hybrid vehicles may include an auxiliary fuel tank, typically used to store an additional amount of fuel for extended driving range or to provide an alternative fuel source for the hybrid system. The auxiliary tank is designed to supplement the main fuel tank and provide a larger overall capacity. The auxiliary tank is typically designed to automatically transfer fuel to the main tank when it is needed. This can be achieved through a transfer pump or other mechanisms that automatically regulate the fuel flow. For example: The 2024 Volvo XC90 Recharge T8 Ultimate has a fuel tank capacity of 18.8 gallons, which is considered relatively large for a hybrid vehicle or something like this… direct from Volvo.
