I've posted fairly often regarding range and towing, and why I believe I need the Max battery pack to be able to successfully tow even my smaller teardrop over longer distances. There is still not a huge amount of data available regarding power consumption and range for Rivian towing, and most of what I've seen is based on towing larger, bulky loads. Their consumption figures are not encouraging, with most at or even below 1.0 mi/kWh. There is a Youtube video of a family towing a 30' Airstream with an R1T that was encouraging however. The figures they posted were in the 1.3 m/kWh range.
I recently had a on-line dialog on another website with someone towing a teardrop that is similar in design to mine, though quite a bit longer, wider, higher and heavier. Their tow vehicle is a Tesla Model Y, and they report consumption averaging 370 watts per kilometer. If I'm doing the conversion properly, that would be about 592 watts/mile and would in turn mean a theoretical max range with a Rivian LR Large pack of 228 miles. Using 80/15 charge/discharge parameters brings effective range down quite a bit, but still to a very respectable 150 miles.
Am I making a mistake in my calculations? As importantly, am I making a mistake using the Tesla as the basis for things? I'd think that the larger and heavier Rivian, regardless of whether it was the R1T or R1S, would better the Model Y, or at least be no worse. With my teardrop being smaller and 1,000 lbs lighter than the one towed by the Model Y, I'd also think that at the least, using the Tesla figures would be very conservative.
The bottom line for me is that if I could get those numbers towing my [email protected] 320 with a Rivian LR Large pack, I'd gladly forgo the wait (which could be indefinite) for the Max to become available.
