    I guess it could go either way. They could try to capitalize on EV drivers. Or they could want to discourage us, due to issues like supply limits.

    I think long-term, charging at RV parks will be something people did in the early frontier days of EV driving. If there was a DCFC at every highway exit / rest stop, why would you stop at an RV park for a mere 7-8kW?

    That dedicated approach would certainly have to be the solution. But as you mention, in the development years, RV parks (especially during temperate months) can fill a gap. But proper management during hot months will be required as there are already power delivery issues for the primary customer base.

    Well eventually I bet RVs will become BEVs too...

    What a PITA it will be to pull up to a charging station and find all the EVSEs occupied by RV EVs charging their 300 kWh batteries! "Just knock on the door when you see we're at 100%, dearie, and we'll come out and unplug for you."

    Same issue once they electrify f350's, f450's, f550's etc...

    But drivers of those trucks may have somewhere to go and won't want to wait for the agonizing, asymptotic last few percentage points to get to a 100% charge. Drivers of RV EVs, on the other hand, are already home.

    I think a BEV RV (I hereby coin the term BevRev) driver who knows he has a 14-50 waiting for him at the RV park will behave like a regular EV driver who has EVSE at home: he'll fast charge on the bottom end of his battery to get on down the road, so he can get to the park, plug in, and then do all the fabled RV activities.

    But, I do see a big infrastructure problem for the parks, in their future. I'm sure their load calculations did not factor for every pad immediately and continuously drawing 40A/240V. Even a modestly sized park with 20 slots would need 200kW of service just for the RVs, before tyou add in the pool pumps, kitchen, and other hotel loads.

    With two BEVs in my household that, after a full day of driving, between the two of them, draw 11.5 kW for about 6 hours, they pull about as much as the rest of my house does at its peak, a quarter of the time. I often wonder how many households in my neighborhood would need to go EV for the lines and transformers in my neighborhood need to be upgraded.

    Here in Houston, electricity use peaks around 4 to 6 pm when everybody's AC is going full blast. We often run the grid right up to the limit and recieve texts begging us to modify our thermostats. But that is the exact time when everybody also gets home and plugs in EVs, and I'll bet they mostly don't set timers for off-peak use. I had a plan with big off-peak discounts, but that electric company went under. When I shopped for new company, none of the plans was especially EV friendly. You'd think somebody would offer free midnight to 0600 power, as that is when a) they need power use to burn Wattage they are generating to handle the day load, and b) by shifting to night, they are preventing the day load's growing. There are some that have time shifting plans, but none that really capture the growing EV paradigm.

    If you have an RV you already know of the brown out issues in RV parks and damage to RV AC units as a result. They can't even deal with current demand. Forget an f350 with a 300kwh battery pulling in towing a 5th wheel needing to change while running two 15k AC units.
