i´m new to the forum and didn´t find any topic about this. I don´t have RAM yet but i´m getting one. Do you use any fuel running preheater in your trucks, electric blockheater is not a option becouse there is no powersocket near the parking space and here in Finland we have 230V. Car have remote start so do i even need preheater? How long it takes to get warm inside cabin when you start motor, let´s say zero degrees?
