This seemed like a good place to ask, vs. starting a new thread. Am sold on a MX 100, and plan to tow with it from time to time. Thanks to everyone who’s taken the time to chronicle their adventures! Instead of an airstream, will be pulling a race car in a small light aluminum trailer (96” wide but only 62” interior height, ~4900lb. fully loaded). I’m in San Diego so there are hills in most directions. The remaining purchase indecision is related to regular 100 vs P100. The P has slightly shorter range in regular use, but I wonder if the different parts would net greater efficiency (thus slightly longer range) when burdened with a trailer? We see this regularly in the ICE towing world, when bigger engines are less efficient unladen, but become more efficient than smaller engines when both are tasked with heavy loads. I don’t have the EE background needed to analyze the hypothesis, but thought I’d raise it to the clever group here. If the P were likely to be able to cover even just a few extra miles with a trailer, might be the last bit of rationalization needed to go with the (otherwise irrational) P.
