    The Model S&X do have an internal pump driven off the gears, but it only works when going forward. So that isn't why Tesla says not to do it. (The Model 3 uses an electric pump with a spin on filter for lubrication.)

    We flat tow an automatic Jeep rubicon
    It has a transfer case, and when you put
    transfer case in neutral, the Jeep just free wheels.

    When you say 1mpg better with a trailer, what’s that in comparison to?

    I have a 4 door 1/2 ton Ram I flat tow. And I’ve pulled my Mercedes E550 on my 22’ aluminum flatbed. Can’t say I’ve noticed much if any difference in fuel mileage. This is with a 43’ tandem axle diesel.

    With my flatbed I’m right at 70’ long. The same or slightly longer than a typical 18 wheeler. No problem going down the road, but limits the campsite possibilities.

    I do agree not being able to back up a flat tow vehicle is a major pita. But I’m hitched and rolling in about 3 minutes (literally). No way you can load the trailer and tie the car down that fast.

    I've noticed an almost +1mpg gain in comparison to flat towing a Honda Pilot on a 20' flat bed with my 40' single rear axle Cummins 350 Diesel coach. YMMV. And yes, as I said, it takes a few minutes longer, but I feel it's worth it for the benefits cited. Again, YMMV.

    I agree that the total length limits the campsite possibilities. IMO, that's the biggest disadvantage.

    Are either of you guy's full timing? I will be in 2.5 years. At that point I think there will be some variant of a electric class A
    Winnebago is already making one but not for the rv world.

    I am sure for me it will be a Diesel pusher flat towing a Jeep. But would love to have a all electric rig at some point.

    No, but if you're really interested in a all-electric solution there are some folks that posted awhile back about towing an Airstream trailer behind a Model X. I recall that it cut their mileage roughly in half, but with the expanding supercharger network, it's definitely doable.

    Yeah I like the class A version better Not really a fan of the trailer camping. However I agree the X and air-stream is really the only way to go all electric ATM.

    This is our setup. Just a note. We know a few people that tow their gas powered smart cars 4 down. All of them have lots of road wear as the coach kicks stuff up and the car wears it. Our Electric smart has just as many miles but is in excellent shape. Its not that much higher but seems to fair better. Takes about 6 or 7 minutes to strap it down. The biggest advantage...I can back up...its a trailer. You can't back up a car being towed 4 down.

    Not that I know of, or that I have heard of. We are actually planning for it’s replacement down the road, maybe a couple years. We were originally thinking something like the model 3 or even the Y but the trade war with the US has ended that. The next version of the model BMW i3 could be a contender but info is spotty at best on what it’s future is. We really like the car and a working 300 kilometre range would be more than adequate (if the do that). The dimensions are not huge but would still require going to a dual axle trailer. In the meantime we’ll stick with the smart. Lotsa fun, convertible, still kind of a head turner.

    I’m running a 450hp Cummins, so bigger motor and bigger coach all around, probably not impacted as much by the weight or drag difference. Next trip out I’ll probably take the trailer again and really pay attention to the mileage.

    There are DEFINITELY pros and cons to both methods, after having done both quite a bit, I would say the Trailer method is preferable, IF you have the room. (Typically I don’t in the places I go) Being a truck driver years ago, it absolutely kills me not being able to back up when flat towing.

    I’m not, only 45 atm, hope to go mostly full time in about 10 yrs.

    The “full time size” equivalent electric motorhome is probably a long way out yet. Basically it’s going to need the tech they are working on in the electric semis, since a big 40’ class coach is running mostly the same equipment. But I do think once electric semis are out and successful, a coach soon follow.

    (Yes, I know you CAN full time in a 22’ class C, but most are doing it in 40’+ diesel pushers)

    would you consider switching to the new MCI J4500e as an RV replacement? :D
