Just think of all the energy you'll get back as you come downhill. Maybe all you'll need is enough battery left to get you back to the top of the hill, and that'll get you home
And who said we can't get a "battery" on a trailer to tow for extra range! (*)
(*) Claim of extra range isn't actually a true claim - just a recovery of previously consumed energy from losing altitude previously gained.

I'd love to see a review towing a 5,000lb trailer up several thousand feet of elevation gain and then seeing how well regen can hold it back going downhill.
A "trailering regen" setting, as in a real down-the-canyon-with-a-load engine breaking would be great! The battery can take at least 135kW at a SuperCharger (empty) which is more than the motor in the car can produce during regen, so yes, you should be able to recoup lots, if not all of the potential energy you used on the way up. Problems w that scenario come with cold, a battery that's already charged, or a car (EV) that's not programmed to take full advantage of the situation, in which cases you will need to use the brakes, maybe a lot! Regen is pretty much gone w a full battery, as is necessary.
Sorry to hijack the thread. I just drive these hills everyday and know that for the short hauls, it's more of an issue than aerodynamics. If you are trailering cross country, then aero is more of a consideration. As is unhooking so you can SuperCharge!

We have a trip coming up, and my wife has her eyes on this:
at about 3600lbs dry weight, I can't see a P90D X getting more than 120 miles on a charge. A bit nerve wracking as one stretch is 130 miles between chargers.

For the long stretch you could drive halfway, ditch the trailer to drive the rest, supercharge and return to pick it up... Would waste 3 hours but give you certainty.
Haha, not sure how it would be received, but certainly an option. I keep telling her there's ALWAYS an option... Just might be super inconvenient.
It would be better to be able to camp for the night in the middle of that long stretch and charge up on a 14-50 at the campground overnight.
Not really worth it for lessth an a 2 hour drive. We'll see as the time gets closer. We may need to stick with a 2500lb or less popup camper.
Haha, exactly. Though, if the powerwall could act like a portable Supercharger, it might just mean a pitstop.

Consider how you might model an estimation of the mileage. For example, you might take into account weight of the camper, weight of the items in the camper, coeff. of drag of the camper, height, width, etc. This might be a useful start to a handy tool for evtripplanner or a good email suggestion for Tesla to offer something in-house (i.e. on the website) to aid shoppers.

Weight won't affect the range a lot, what will really bring down range is drag. So a smaller cross sectional area will improve range drastically.
