I installed an Ecohitch on my 2018 Model S 75D a few months ago. Up until this weekend I had only used it for short trips around town, so I hadn't had any data points on how my range was affected. This weekend I did my first out of town trip carrying bikes. I was carrying 3 mountain bikes, say 30lb each, on a Saris Thelma hitch rack, which weighs about 37 pounds. Plus 3 adults. My range is normally 230 miles. This trip was 100 miles round trip in central Texas, so no mountains or anything. Started the trip at 100% and when I got home I was sitting at 36% battery. This means that my total range would have been about 156 miles. Just wondering if this kind of range hit is what other people have experienced when carrying bikes.
