A 5-fold difference?! Towing a trailer makes the Tesla use 5 times more energy per mile!? This can't be right... Author must have a trailer loaded with a literal ton of cargo.
Edit: a Tesla Model Y is 4200 lb. The trailer is about 3000 lb empty (thanks LukeShu), say worst case 4200 lb loaded with cargo, so at most the weight difference can account for a doubling of the energy per mile. It seems hard to believe drag alone can account for another 2.5x increase in energy per mile, which is why I think there must be even more cargo. If not, I guess for me this highlights how good the aerodynamic design of the Model Y must be. This also means the author could get a significant range increase simply by choosing a better trailer with a lower drag coefficient. Or my preference would actually be getting a vehicle designed for that lifestyle in the first place, an actual camper van. One could even use the comfortable driver seat as the office chair, instead of transporting an actual office chair. Swivel it toward your desk behind it and, bam!, instant office desk: https://www.thewaywardhome.com/wp-content/uploads/2022/12/Sw...
