I'm not going to blame the salesman fully as the nature of solar systems depends on the install. There are some rigs that still have phantom loads when battery disconnect is off, whereas others that it kills all 12v items. I know my solar setup continues to charge my twin 6v batts even with the disconnect off but that's because I wired it that way. I don't know of any rv's that come standard with solar so its up to the selling dealer how they wire the system. That includes fuses, charge controllers mounts, wires etc. There are many calibers of systems and also skillset of installers doing the work. Before I took the word of someone who is selling the rig I would research the system to ensure it met my needs. Solar is awesome, I wish it was standard or at least properly pre-wired on all rigs.
Lots and lots of RVs come with solar standard these days, this has been especially true since late 2019 when the industry started a large shift to 12V compressor fridges. Even the ones that don't come with it are generally solar prepped meaning the wiring is pre-run and all the dealership has to do is pop in the charge controller and slap the panels on the roof and done. I've even started to see some manufacturers pre-install the roof rail mounts as part of the build process which literally makes it plug and play.
All that is a way of saying it's something they SHOULD know about, but since they can't be arsed in general to learn safety critical things like truck ratings I'm hardly surprised that they don't bother to learn how the solar system works.
