Talking of batteries. I don’t understand why trucks, with all the gizmos that are used when parked up, don’t have dedicated leisure batteries, with separate starter batteries. One big 120 amp leisure battery and a split charger can’t cost more than £200 to install at the factory. More than enough power to run a TV, laptop, phone charger etc overnight.
That’s £199 more than my boss would spend on extras [emoji57]
the radio will not flatten the batteries - but with the ignition on, all the electronic nonsense associated with modern vehicles may run the battery low. As others have said, usually the radio works on the first click of the keys, that would probably be OK. Alternatively you could always rewire the radio to a permanently on source (there is a couple of wires that can be swapped on some radios where the backup becomes the main, check manual) But this has its risks too, you could leave it on all weekend and that may flatten the battery.

Scania are already doing that on some models a 14 plate R450 I had the other week is run on 4 small 12 volt batteries 2 at the front dedicated to starting the engine and 2 at the rear of the battery box to run everything else, not all have this system the 64 plate 450 is on a big pair.
Blimey 
Yes if you have your 4000 watt speakers whacked right up it will probably do your batteries. 
Did you used have a small radio at one point that ran for weeks on a couple of AA batteries?
No your 24v batteries won’t give in by playing you to sleep!
Get a grip man!

You think that would be standard on the big cabbed tramper trucks.

At the risk of ruining some possible light trolling, of course itll flatten it
Your unit might have a low power cut off to protect the battery but id be surprised if it didnt and your battery lasted all night right through to the morning.
220Ah of battery available at the very least. Radio draws 1-2 amps. The batteries on a truck could keep the radio running for a week.

Night heater runs on a seperate system though doesnt it?
No, it uses the truck batteries for the blower and the heater element.

You may not need the ignition on. I leave the radio on when I night out but with the ignition turned back 1 click. Its never been an issue but that said, any issue would be an easy fix for me. A jump start via the Anderson lead but obviously a rigid wont offer that peace of mindAs long as you have a truck with an Anderson connector parked next to you…
Dont need truck with anderson lead just put anderson plug on jump leads ,and you end up with jump lead with plug in middle
