More on the topic of water being some kind of limitation for length of say off grid. Here is a version of the same approach I have taken to eliminate water as a limitation.

Now we just need to know what pump the Lightship has so we can get a spare

We also need to consider the effect of weight transfer from the fresh water tank to the gray and blackwater tanks. I assume the gray and black are behind the axles, and that would decrease the tongue weight of the trailer, which will increase the propensity for the trailer to sway.

I completed a 300 mile trip to day in Arizona towing the LightShip 4. For this trip I used the LightShip battery only with the air conditioner running while in motion. For this leg I did not hook up the NACS port to the Powerboost, I just ran on battery alone. The solar panels were active satisfying all 12 volt demand while taking the 12 Renogy battery up to 100% SOC.

I departed with the high voltage battery at 93% SOC and arrived at 84% SOC, so I consumed about 7 kW on the trip over the 300 mile trip, mostly supporting the HVAC unit that was set at 73F. I was seeing nominal demand around 600 to 900 watts. Outside temperatures were in the mid 70's during most of the trip.

On a 100 mile segment beginning and ending at sea level, with light winds and a speed target of 62 MPH the fuel economy was 16.7 MPG. I never used TrekDrive on this trip.

The LightShip tows very well. Compared to the Airstream it feels like you always have a strong wind at your back. When I let off the accelerator there is no sudden deceleration like a feel with the Airstream because of all the wind resistance pushing on the Airstream

I also feel much more comfortable towing at higher speeds with the LightShip. With the Airstream I felt uncomfortable going more then 62 MPH. Today with the LightShip I found my cruise speeds feeling natural up to around 70 MPH.

And the heads were turning at the gas stations. It is interesting to watch people when they first see the LightShip. I think many people are trying to process what the machine is at first glance.

Can you show your fuel economy in hand calculated numbers. Most computed mpg's are usually inaccurate and overly optimistic. Hand calculating should show numbers to a hundredth of mpg.

I don't use the Ford dashboard mileage calculations. I use an OBD reader and OBDLink IOS App to measure fuel economy and many other parameters not available on the standard Ford instrumentation. I have independently verified OBDLink calculations to be accurate down to two decimal places.

Below is the 100 mile run I made and reported in an earlier post.
