If you don't use the air/con or heat, probably indefinitely.

If you need air/con or heat, well, not so great.


What if you need to prepare meals?

The stove is an induction cooktop. That's an energy pig.

What if you need to keep your food from spoiling?

Compressor-driven refrigerators aren't exactly power-misers.

Its a gimmicky trailer that only a few tree huggers will buy at that price and feel good about how they are not leaving a footprint by having a green trailer.

If I am going to spend 80K on a rig it certainly is not going to be that one.

While the focus is on energy I hardly doubt it's green. Manufacturing techniques, caustic materials, glues, VOC's. etc.

And it is a bit of a head scratcher. Why would you opt for inefficient appliances when decades ago stoves and refers were developed for RV's for the sole purpose of being efficient. All electric RV's exist today. All you need is more solar and more batteries to arrive at this point. Sorry, I don't get the concept.

According to the website, the base model is 7kwh (7000w-hr) battery bank and 600w solar.

If you are doing long 6-8hr slow simmering meals, it could be a bit of a problem.

Assuming the stove uses 1500w for an hour on high (longer than it typically takes us to make most meals, that's pretty viable with a 7000w-hr battery bank. The 600w solar system should put back in around 2400w-hr per day.

Our 12v fridge pulls around 60w on a 50% duty cycle in comfortable conditions, so around 720w-hr per day.

It's when it gets hot or cold that battery power becomes problematic. An air/con pulling 1200w with a 50% duty cycle is going to pull 14,400w-hr per day. Assuming they are heating with a heat pump, expect similar consumption. So it would need a substantial upsizing to the battery bank and solar array to keep up or they need to undersize it but then the duty cycle goes up. If it's small and insulated far better than I expect, it might be possible but you will always have to be watching the batteries so you don't run them dead.

Run of the mill RV's are already going electric except the stove and furnace. Even a lot of them are coming standard with 12v fridges now.

None of what you're describing comes anywhere close to meeting the definition of "indefinitely".

If there is no sunlight available, no amount of solar panel "upsizing" is going to help.

You are going to run out of power.

Interestingly, they don't list the cooling capacity in BTUs - Only in "watts of cooling power".

If you use the standard conversion factor of 1 watt being equal to 3.41 BTU/h, their larger "Comfort RC" model with "2400 watts of cooling power" produces 8200 BTUs - Which is around 60% of what a typical RV air conditioner produces.

Here is what this trailer manufacturer says about their exterior construction (insulation). Also, the floor plans have no slides (air leaks).

RXP construction
No R values are reported.

I think that som of you need to read. It says power by 14k Battery and 1600-2000w of solar. I have a Glendale Titanium hear in Australia. It has been partly converted to Australian 240V supply true a step down converter. Fridge is a 240V household Mitsubishi inverter type, as is TV and washing machine running of a 375W inverter 24Hours a day. Rest is 120V. Also has a 3000W 120V inverter for microwave etc. batteries are 300A lithium. Power use about 100A in a 24 hour period. Solar is 600W. This normally is adequate to recharge batteries if not I have a Honda 2.2 generator that charges via my 125A charger. Many hear instal reversible 2500W inverter air conditioner in there FW and report better cooling and less power drain. And lastly hear in OZ we do get a lot of sunshine.
I am not running out to get on but do realise this is Australian and you don’t get much van for under $100000.
Have a good day Frank..

In OZ, do RVs not stay cooler when they're parked in shade than in sunshine?

Do not most RVers in OZ prefer to park in the shade, for this reason?

1 yes possible. But solar panels also create shade for roof, so are you saying that Americans park there vehicles with solar in the shade, I don’t think so, and I never did if wanting to charge batteries.
2 yes manny people park in the shade, but most don’t have much in the way of solar and live outside there trailer only used as a bedroom.

As far as toilet goes most al places has som sort of toilet, or you have to be fully self contained, most of those places also has a time limits for staying, drinking water can be brought in by containers or water bladders if not wanting to shift trailer. Camping is only allowed in designated areas, but overnight can be done in roadside rest area's.
