Regarding "range comparisons" between EV daily drivers and fossil fuel daily drivers: Our daily driver must be ready for anything anytime (cuz I can't afford multiple types of daily drivers) ... not just running around servicing life's routine errands/work/etc..
i.e. We don't fly and we don't rent and we don't bus and we don't train, so how do we make unplanned/emergency long road trips to other states? For around 6 years we had to make multiple 1800 mile round trips to help care for my dear mother-in-law before she passed. We have other loved ones a long ways away that it's best we be able to visit for whatever reasons, if needed, at the drop of a hat.
When an EV has a 500 mile range in cold or hot or normal weather - with no access-wait charge up stations all over the place and a 15 minute charge up time -> then EV's will be ready for prime time. Until then, they're merely a niche market vehicle for specialized/restricted transportation use ... IMHO.
FWIW, what the transportation world needs most are batteries with energy storage volumetric densities approaching that of gasoline and diesel fuels.

Best you can do?
Lithium batteries are not always RV friendly, they do not like HEAT nor do they like COLD, they like basically "room temperature".. How many times have you personally camped when the max and min temps were 70-80 F all day and night?
So, to keep Lithium batteries happy you MUST COOL them when they get too hot (waste energy) and when they get too cool you MUST HEAT them (waste energy).. neither is ideal..
At least with Lead acid they CAN be charged and discharged at extreme temps without the needs for temperature controls that monitor and apply heat or cold when needed.
Better buy into the Lithium is best band wagon with your eyes open, charging Lithium batteries in cold temps can destroy them in a second.

Combined with the typical poor installation and running the inadequate ducts in the super heated roof cavity, the RV units are inefficient power hogs. An efficient mini-split system should provide better cooling and use less power. EV A/C systems are very efficient using variable speed compressors and computer controls.
my question exactly. if a car AC can be run on battery power plus move the car, why can't that battery run a larger AC ??

If I suggested golf cars should be diesels because they would have 4 days of 36 holes range without refuelling, that would make sense, right?
Part of it is we get stuck in our ways. Is an electric vehicle that has a range of 500 km sufficient for road trips? Sure it is. But you may have to change how you do things a bit. We occasionally (rarely) have to do a 800 to 900 km road trip. Long day but doesn't take any longer than with a gas vehicle. The only difference is food and rest/pee breaks are done concurrently at charging facilities. Eg, before going into the restaurant (or in our case the lunch we bring in our 12 volt cooler) we take the extra 8 seconds to plug in to the charging facilites. Wether its a 10 minute pee break or a 20 minute lunch or supper break you use the time to recharge. Can't really do this at a gas station because you are supposed to not just leave the car at a pump. Not so with an EV as you just plug in and walk away.
Its not a big adjustment and the benefits of going electric are huge.
Yes - one episode of the podcast I referenced discusses another general study of personal cars used for work commuting, trips,etc. I don't remember exact numbers but out of something like 300 days used in 365, it was 6 or 9 times were trips that would challenge existing BEV range capability...
Anyways if I had a BEV, I could have a nap while supercharging on a trip, no problem.
Non Tesla BEVโs are ok for naps while fast charging as they charge slower and the chargers are slower. Itโs tougher in a Tesla though unless you have run the battery flat and your looking to get every las amp in the battery. (Charging slows down a lot over 90 percent). To date our longest Suoercharger stop has been about 20 minutes ish. Short nap.

One of the reasons Lead Acid recycling is 98% is that we have actual laws.
Now you the consumer do not see the law so much as the stores do but you know what CORE is? When you buy a battery and install it you take the old one in for CORE exchange (refund) or in my case normally I take the old battery in, buy the new and then install (on the RV, on the car I let the store install) so I get a "Discount" for returning the old battery to the store.
NOT so with LI batteries
And we have a "Throw it in the trash" Mentality so they get thrown in the trash.
IF we had CORE return policy on LI's More would be recycled.

What in the world is the AH capacity of fully charged Tesla car batteries, anyway?
In the RV world, the electrical power consumed by air conditioners and electric heaters is so astronomical as to be nearly impossible to consider them being powered for any length of time by RV battery banks regardless of the physical size of the battery banks.
How does Tesla cram that much lithium battery power under the floors(?), in the fender voids(?), in the underhood void(?), and/or under the trunk floor(?) so as be able to power both the car and A/C or heater on long trips?
I find it hard to believe. :h
