OK, let's look at this again. At first most of us interpreted that you measured 13.4 volts on the output of the converter. In order to do this, the converter would have to be running, so that has to mean that shore power is already connected, otherwise, with your narrative it would read 0 volts. So is sounds like your converter is powered and seeing no load, including...no battery. That
could be OK.
Now when you hook up the battery and the loads to the coach, the voltage (at the battery or at the converter) drops to 12.6 volts! Now that
could mean that your battery is soooo dead that the converter can only manage to supply 12.6 volts and is attempting to charge the battery and cannot summon up enough current to get over 12.6 volts, or it could mean problems in the wiring or the converter itself.
Of course by now either you are still at 12.6 volts, or the voltage has risen if the converter has managed to push some charge into the battery. 12.6 volts is really really low for the output of decent converter (S/B 13.2 or higher) when connected to anything but a totally dead battery but pretty good for a charged battery without a running converter attached.
What is the status now?
