Took the truck out on another test, this time steep hills and lots of narrow roads. Took the kids biking and some other fun activities as it was their first day off from school. Welded a hitch on so I could fit the bike rack. Working out well so far and it very much out of the way. Pulling...

I was careful to be within the pump requirements, but will keep this in mind!

Just have to convince the wife I need an m1087!

I did! Look at the first picture (after all the harassment I got last time I remembered to do that) but then messed up attaching the European version 😄

Inaugural trip! A small trip down the road to test out all the systems, not some epic overland adventure...yet. Overall it went very well. The boys found a random girl and played with her for hours so that was all they needed to be happy. Beds are a little firm so putting some memory foam...

Been working basically whenever I had any free time so haven't been posting progress. Got all the storage boxes mounted, all are 24"x24" cross section and lengths of 3' (behind battery box), 4' (behind gas tank) and 2x 5ft both sides - rear. Ended up mounting them to the box versus the frame...

The whole reason for this project, the memories :) had a dinner pizza party with the family! After 3 hours of TV, AC, getting Spotted Cow from the fridge, battery was 99.3%. really curious how it will do in winter but summer is no problem for the electrical and solar.

We really want to use this thing soon so mcmaster has been getting a ton of orders and I've been working non stop. Heat pump system still working awesome (never more than 10% battery use overnight but weather has been pretty mild. PWM light control is working great and using an insignificant...

Made up the covers for the electrical area, all quick to pull the off for full access. Mounted the control panels as well, the Victron unit, the Arduino screen and keypad, then the general use panel (phone charging, e-stop, cigarette plug, amp connectors). The largest black section is the heat...

Victron system gives some really nice data. Dropped to 40°F in the evening the other day, from the time solar went away to it coming back the next morning, truck had lost 10% battery from running the heat. Batteries were back up to 100% by 10am. Seems the high efficiency of the heat pump and the...

Lots of cutting and grinding to fit the sink into a harbor freight tool chest.

Batteries have an air gap of several inches, they all have individual temp monitors inside as well. For forced airflow, I have speed and direction control of the heater matrix so if I need to cool, I can suck cool air over them, or turn on heater and reverse air flow if heating needed.

Took the truck to a kids birthday and gave him a ride home (he loves army stuff). Boys testing the electrical system. Learning how Node-Red works to set discharge limits on the batteries. Using this I can interface and control everything in pretty much any way I want. Finally got around to...

Fun milestone today, charging the electric truck from the....military hybrid diesel-electric truck? Try to guess our political leanings 😄 Lots of learning to do as there are tons of options with the Victron equipment. Generator and shore power inputs are up and running.

Been working hard on the truck trying to get it done soon so we can go on adventures, haven't been taking many pictures though. Mcmaster and Amazon love me right now. The storage boxes came in, still need to mount them. I maxed out the size so need to be careful with clearances. All 24"tall...

I'm not adding up the costs as I go, that would ruin some of the fun!

Got the batteries, a bit over 15 kWh. 300lbs so was considering where to place them to keep passenger/driver level but habitat corners were within a few mm to the ground so doesn't look like it matters much.

Got a few of the storage boxes for the interior (harbor freight) unfortunately one came dented but too much effort to return and wait for another few months so a hammer and paint is the solution. Also mounted the air/water heat exchanger. Rock solid with the unistrut. Got the motor drivers too...

Problem with series is shade, have lots of deciduous trees around here so if a single panel is shaded, it would kill half my output. (From my very limited research) I plan to look at some technical reports, forums seem to be ripe with opinions instead of facts from the RV community.

MPPT controller can handle 250V, each panel is 48 VOC per datasheet. I could easily do 3 in series in 2 sets with lots of headroom. I'll probably do 2 in series with 3 sets - to optimize generation with shading. Each panel is just below 10A so I could run the 3 sets into one set of cables and be...
