Fold Up Tow Bar Part 2

Ok that's another job done, the metalwork is finished and painted and it's all installed on the truck.  It turned out quite well.
Just a couple of hydraulic pipes and some electrics to go.

Fold Up Tow Bar Part 1

Had a bit of time to mess around with some heavy engineering this week.  I wanted to fit a tow bar to the rear of the truck so i can tow a Suzuki Jimny.

I was already toying with the idea of making the rear underrun bar on a hydraulic system so I can lift it out of the way if I need to.

Now i am thinking that i might be able to do both the tow bar and the underrun bar at the same time, its a work in progress.

the plan is to make a hinge using a 24mm bolt as a pin, this will bolt on the rear of the chassis, the drop plate is a bit of 6" C channel, i will attach a ram to the back of the channel to lift it all up out of the way.

This is as far as I have got:

victron energy Inverter system

As the truck is all electric, that is to say, the cooking is done with electric, I needed a robust and scalable inverter/charger system that was totally reliable for the job.

After several months of research and investigation into both Victron and other systems, I chose the Victron Energy products, the main reason was how versatile they are, and the fact that they fitted the job perfectly.

When the 24v 8000W Victron inverter arrived, I was very pleasantly surprised at the build quality, it really is a fine piece of engineering, it looks great and the functionality is even better.



I coupled the inverter to the Victron Colour Control Unit, this allows monitoring and adjustment of all parameters of the batteries, inverter, solar controller, generator etc; and even uploads the data to the Victron VRM internet portal so I can look at the status of everything and remote control it online.



The Victron system has so many features it's only possible to mention a few, I think apart from the VRM portal one of my favorites is the “power assist” feature, this allows you to set the amount of current you draw from a wired connection (at a campsite). If you then need more power than this connection can supply, The system will supplement it form the batteries - this occurs seamlessly without you even noticing.

I essentially wanted an 8kW inverter system to be comfortable running the cooking and heating, refrigeration and aircon in the truck. I estimate the maximum usage for short periods to be approx. 6kW

This inverter system is backed up by a Victron 1000Ah AGM battery system, I was going to go for a Lithium-Ion battery system but I don’t think the budget will stretch to it.  (That's all changed now)



A 6kVA diesel generator supplements the system when needed and can be automatically started and stopped by the Victron system when needed.

There is also 2100W of solar panels connected via a Victron smart solar controller to take full advantage of the suns energy.

This entire system will allow the truck to run with all the comforts of home totally off grid for an unlimited length of time.
