Same issues here with temperature at-11 on late December. I keep it plugged overnight and I have no problem with during the day. I have to mention that one day I have 0.8 miles/KWh efficiency for first hour or so…
I was keeping my Tundra’03 for several months but I got rid of it (donated for $1). Regarding long trips…cross country trip and NO issues with R1T. Just find the “sweet spot” and ur good to go ?
Full electric here. R1T and Nissan Leaf ‘18. No regrets on the decision. More than that, in May I will have a Canadian trip with my grandson and, hopefully to reach 30k miles ?
