What the Outlander is good in?
For me in 2018 it was the only car that could do short trips fully electric. Do long trips without charging stops, had all wheel drive for Canadian climate and was able to pull my camper!
Today we have more choices and a Rav4 Prime could be an option, if only you could buy one! There is a huge waiting list in Canada.
So would I buy one again today? I'm not sure. I use fuelly.com to compare real world energy efficiency. And it seems that my premium in purchase price is still not recovered after 6 years, compared to an ISE Outlander. So, what has made it worth it for me, is that the electric drive is comfortable and quiet. I had electricity at a campsite that was non-electric. So far it has been extremely reliable. And charging at home means, I always have 25 km of driving range on cheap overnight electricity.
As for backup power. V2H is too expensive for the average home owner. I also did not opt for the build in converter at the time, because 1500 W would not be enough for the house. (So Woon, in my mind you did not miss out there.)
For a home backup generator I would consider LPG, as that fuel is better to store than petrol/gas. I remember the days of peak-oil and that we would be running out. We have these days more oil and gas, than we can burn, so I'm not too worried about the supply. I'm curious what you had back first gas or electricity in case of a major black-out/disaster?
Just my 2c.
