How are you not finding Tesla chargers? If you use the phone app, the website or the in-car app, you'll see several super chargers. There are 2 in the Burlington area, one in Montpilier, one in Rutland, one in St Johnsbury, one in Battleboro, and probably others. If you settle for level 2, you'll find many more.

Do you have the CCS adapter? There are a few non-tesla DC chargers at tourist areas, like Ben & Jerry's HQ and Alchemist Brewery, and probably others closer to your destination.

Coming from NJ, the Battleboro supercharger is probably the closest to your destination. Top off there, then use level 2 destination chargers when you can find them. Worst case, plug in to a regular outlet overnight, you'll still get ~4 miles of range per hour.
