Math : 4000 km road trip. 1600 km of that is towing. 30 days for the trip. <150 km per day.
Total time spent "waiting" for a charge = 0 hours and 0 minutes.
Reason : We eat lunch/dinner, and we charge overnight while staying in hotels and camping.
I've done >30000 km in RV's, majority of the time I am waiting for the kids to eat or download stuff on the free wifi at rest stops prior to continuing journey.
I have more than a enough time in the seat of 20000 lb vehicles to know that I don't enjoy $500 daily gas stops.
Total charging cost estimate is $200 for the high speed charging through Ontario and Quebec.
Estimate for gas is $1500 for the same trip.
If you aren't retired, I guess you can stick with gas, that's what I did. Now, I'd rather drive in quiet powerful comfort.
