No....almost all of the maintenance on an RV is already based upon time not mileage. All the parts mentioned simply “age out” by sitting.... imagine if the only RV maintenance you need every year is to check suspension and grease a few fittings ?

Why would you need propane? The huge batteries on board would potentially run everything while boondocking.

We have a diesel aquahot to heat water and the coach when it is cool while on the road and Wally docking. If all you have is batteries your margin for miles just dropped significantly. Unless you are going to carry fuel of some sort and a generator.

I would think you still need your bank of 6v batteries for coach power. The drive battery would be isolated.

It doesn’t have to be. It would seem silly to have 500Kwh of lithium batteries in the chassis and then have some 6v lead acid batteries to power the lights in the coach

I want one!
But not until it's about 5 years old and all of the bugs are worked out, like shade motors.

Would love to see Newmar build an interior like the new Winnebago Horizon

Here is a little Tesla Semi acceleration video. Kinda cool.

I would like to see the electrical requirements to charge the batteries for a 400 mile day. I read where as few as 3 of the Tesla cars on a block in an older neighborhood would brown out an older electrical grid.

Good evening DGB. I think somebody got confused. A tesla comes with a 40 amp 240 volt EVSE for charging that can be plugged into any stove plug. You can also get a HPWC or high power wall charger which draws 48 amps and needs a 60 amp circuit. There are a few Teslas that have dual chargers that can pull up to 72 amp but these are not usually residential setups.

I suppose it is possible if there was some kind of engineering issue by the utility but assuming that if the owner has a 14-50 stove plug installed he/she probably has a 200 amp service on the house and the neighbourhood would be designed for that. .

If he only has 100 amp service he can dial the EVSE back to whatever he can provide, eg, 30 amp, 20 amp etc. There are lots of EV owners with 100 amp or less service.

By the way, EVSE stands for Electric Vehicle Supply Equipment. All EV's come with them.

No idea on the Tesla Semi requirements but probably similar to what all the new ELectric busses use. Liquid cooled connections. 350 KW. Probably multiple feeds.

Without a doubt. Electric motors are the future. SO much less maintenance, insane torque.

I think eventually electric vehicles will be much cheaper to build than conventional ones. Especially heavy weight ones like Semis and RVs. The increased cost of the batteries are offset by not having an Engine, transmission and drivetrain with a bazillion moving parts. Electric motors are much simpler in construction.

Elon Musk made a passing comment about the brakes on the Semi. He said because of the regenerative braking, the brake pads will never need replacement.

I checked out the Horizon. Very nice updated look. I would love to see Newmar offer a contemporary modern design option like that.

I agree with the suggestion of having a diesel genny to top up the batteries. This could extend the range considerable as well. Diesel electrics are common place around us everyday. Almost all trains in use are electric drives with diesel generators to supply the electricity. Also large mining trucks and many ships are the same design. Apparently they cant make a transmission large enough to take the torque required to move such large equipment.
