Need instruments

It's a good idea to have some idea what going on with your electrons. The hard wired meters discussed here are great (trimester 2025 rv and such). But if not that ,at least get a decent multi meter and preferrably a clamp meter like a 320 Series True-rms Clamp Meter, by fluke. You can check tour voltages your current draw ( eg parasitic loads) etc.

I have had my fluke meter for nigh on 30 years and take it everywhere. It does home auto and rv with equal flexibility.

Here is another possibility. The battery should have been charged when driving however with my first TV (2004 GMC Sierra 1500) there was a fuse that had to be installed in the fuse block to allow the battery to be charged while driving. It was a 40A fuse.

Not sure how long your rig was actually parked but it would be interesting to know what the parasitic current draw is. Then it is simple math to determine how long the battery will last without being charged. Other than the booster, the other draw is the CO detector.
