Making the switch to a PHEV truck is a wise, eco-friendly choice, especially with the concerns you're raising. There are a few solid options like the Ford F-150 PowerBoost Hybrid, which, while not a full PHEV, provides a good balance of fuel economy and towing capacity. PHEV SUVs, like the Mitsubishi Outlander, are also worth checking out if you're open to alternatives.
Regarding towing, PHEVs can offer close-to-gas models’ capabilities but check specific specs since it can vary. Infrastructure for charging in rural areas is still catching up, but home charging stations are a great solution. Maintenance overall could be lower with less demand on the combustion engine, though ensure battery care and longevity are covered in any warranty.
Reliability in harsh weather is generally solid, but battery range can reduce in very cold conditions. I'd suggest test-driving a few models to see what fits best with your needs and lifestyle. Don't forget to explore possible incentives, too, as these can significantly lower costs. If you want more tailored advice, engaging with owners on forums dedicated to specific models can be incredibly insightful.
