First of all, I agree completely that there are a lot of places in the midwest that are still hard to reach by EV. It is the round trip without charging at the destination that is generally the challenge as one can almost drive an LR Model 3 all the way from I-80 to I-90 on a single charge if driving slowly.
As with most things in those areas, the locals need to take care of themselves since there isn't enough traffic for 3rd parties to be able to do it profitably. RV parks and welding outlets tend to be the best options. Also, keep in mind that a lot of small rural towns have city parks and fairgrounds with RV hookups. Often times, these are not listed anywhere. Sometimes they are only '30-amp' outlets which translates to 120volt, 30 amp TT-30 outlets. Tesla doesn't sell adapters that take full advantage of them but evseadapters.com (TT-30 Adapter for Tesla Model S/X/3/Y Gen 2 – EVSE Adapters) does. It will charge a Model 3 at about 10 mph. Having a bunch of adapters is essential.
As always, PLEASE list anything you find on www.plugshare.com to help open these areas up.
Another tip of the trade: If only slow charging is available, you'll generally get to your destination faster by driving slower. The optimal driving speed is about the 240 volt current. In other words, if you'll be charging on a NEMA 14-50 at an RV park at 40 amps, 40 mph is about your charging speed and your optimum driving speed. If you'll be using a 30 amp J-1772, 30 mph is about your optimum charging and driving speed. Clearly, these speeds are often too slow for practicality so you may spend another hour of time checking out some small town than you would have to.
