21 VNL860 upgrades, mini split/battery APU

Agreed, that yellow hose is a charging hose, not a service hose.

Those black flexible hoses look great and could probably be unmodified and hidden between the interior back wall and the outside wall. My truck, at lease, has quuite a gap there.

I talked to 2 hvac guys about modifying the length of the hard lines on a precharged unit and both said it would not be enough volume change to matter.

So far they were right. I used about 2' of the 16' coil mine came with and cut the rest off.

 

Finally getting some hot muggy nights to test this thing. I got off the road early yesterday and ran it from about 6 pm to 7 am this morning, pulled between 10 and 40 amps depending on compressor cycle. Took my batteries down to 70%.

 

I've heard the same but there are also people who have been running mini splits for awhile now without trouble.

To be clear, I never run it while driving. But if I did and it could damage the compressor, why would it matter if you were driving or not?
I've wondered about this for awhile.

Fridge compressors do fine running while rattling down the road for years.

 

Sorry, I haven't checked this thread in awhile. A few months now with this setup and it's working great. Still silent, efficient cold AC. I typically use about 15-20% battery overnight but if I'm down during the afternoon the hottest hours of the day will really suck it down. I have seen it drop 20% in 2-3 hours at a slow dock but as long as I drive a few hours after it's back up by the time I knock off in the evening.
