Here's a thread for pics of stock rav4h w/o any addons or mods.
You got any pics of your door sills?Here You have Svarten, when he was brand new, in may 2016, (name translates to Blackie, named so when I joined Fuelly and they wanted a name). Took some more pictures but sadly lost them in a phone change. The only upgrades to this day is steel door sills.
I paid 7300kr and the parts retails at Mekonomen for about 3800kr.It's a Active, https://www.toyota.se/nya-bilar/rav4/grade/ha-rav4%20hsd How much did you pay extra for the DEFA system? I declined that due to price, they wanted 10500kr so I just ordered cables and socket for cabin heater installed, figured that the engine heats it self. I got those steel Door Sills from Amazon UK, did not like the original aluminum ones that Toyota had.
I just installed the Inner door sill guards OEM toyota ones with LEDs.I paid 7300kr and the parts retails at Mekonomen for about 3800kr.
I will elaborate with the fuel economy, on my ride to work I always check after about 10km what the current average is, on my previous car a Forester 2.0 Turbo it went from 0.9/L to 0.7/L due to preheating.
Defa is a modular system as you may already know so you can get an Y-splitter if you still want to add the heater later on if it turns out to be great.
I might clone your Door Sills, I usually mod the **** out of my cars.
