Tesla Supercharging was the primary charge station type used. Model S towing over 7,000 cargo trailer. Total weight of full vehicle and full trailer 12,240 lbs. 6 of the 7 EA station layouts did not accommodate well for towing a trailer. The one that did was a pull through station in Kalamazoo MI.
The layout problem isn't only an EA problem. I haven't bothered reading this but Edmunds had trouble with Supercharging with a trailer attached as well: https://www.edmunds.com/tesla/model-x/2 ... ailer.html
It stems from both the layout and where Tesla decided to put the charging inlet, in a stupid location, if you ask me. No Tesla is based upon an ICEV so it's not like they were reusing the location formerly used by the gas hole. In my almost 6 years of driving Leaf and now having a Bolt since end of Jan 2019, I'm convinced that driver's side front fender is way inferior to in the center of the nose, at least for most US public and workplace charging setups. I explained why at https://www.mynissanleaf.com/viewtopic. ... 12#p548912
w/a crude drawing.
The other locations are even worse. Not only does Tesla often force you to back in, which might be tricky and slow in a busy crowded area, it's also the on the wrong side for street side charging (if it's on the right side). Fortunately, street side parallel parked charging isn't common in the US.
If they put in the (or another) inlet in the center of the nose, some of of the problems Edmunds encountered would've gone away.
