So I am about to embark on a very long road trip in my 2008 4runner and I have everything setup as needed except I am trying to figure out a way to have heat without running the engine for sleeping at night.
I am going to do most sleeping in either tent at camp sites or in the back of the 4runner itself which I have setup to make almost the entire back a sleeping area so its very comfortable, only issue I need to solve is how to have some heat during the really cold nights say anything below 25-30deg F, I have good cold weather gear and a great sleeping bag rated down to -15c but I don’t want to have to “Survive” I want to be able to sleep comfortably and be happy as possible when I wake instead of fighting to stay warm all night, even a small amount of heat like say a heated blanket or very small ceramic heater would be perfect, but I am not sure what size battery I would need and a way to hook it up into my car system so it charges while I drive, I am pretty familiar with these setups from research, but don’t know quite enough to determine the need for such a small vehicle compared to a full Ford Transit or Pro Master.
Anyone have any ideas they could share on how I could generate heat even a small amount in a 4runner at night without running the engine? Say from like a heated blanket, or small ceramic heater, or something like that. I know they draw a ton of power, but it’s the only forms which don’t give off toxic fumes or open flames and such.
Thanks for any help! I really appreciate it!!
