Use public charging spots? Not sure where you are located, but here they are everywhere. An AC charger is always <5km away, in the city/towns usually <500m. You only need an adaptor cable and a tag/app to unlock them, but it's cheap and easy. And if you're in an RV you can easily park around them without having to take all this weight with you.
Here (at least in NL) about all of them provide at least 16A @ 240V, most of them 3-phase (3x16A) or more.
Might differ on your location tho, somewhere in the canadian forest availability of charging stations is much lower off course.
Here we have about 80.000 available public charging points or so in our tiny country. (and 200k+ private or so, but many are also available for other customers)
Only the adaptor to convert to a regular socket and an extensioncord needed, and for the price (here about 0,35 euro / kWh or so) you can't drag 5kWh of battery with you.
You only need a decent charger if you want to 'fastcharge', but that also applies to charging in a public libary or similar.
In my opionin, public charging points are even more convenient since you can do shopping / having diner or whatever during charging, where as at a libary you probably won't leave the battery charging unattended.
