I’ll add that when we were on the road traveling full time for 2 years (‘19-‘20), and pulling a travel trailer, we often plugged the trailer into less than ideal power supplies.
I ended up getting one of the Progressive Industries 30 amp EMS surge protectors like the one referenced above, it was nice to have the piece of mind and it definitely saved us a few times by shutting down and showing faults before any damage was done. We sold the trailer and I included the surge protector, along with a lot of other goodies, in the sale.
For some reason, I have not used a surge protector when plugging in the van, even to 30 Amp, except for a few times when we had the trailer and used the Progressive unit I had to top off the van batts. For one, it was quite bulky, but I may get a smaller 30 Amp unit to stash away in the van or at least this tester and module kit

But I will say to the point about the link to the surge protector that caught on fire, the key operative point there was that it happened after a hard rain, water and electricity do not mix, that unit in the photo didn’t seem to have a protective cover, at least not any more.
@Steve Hunt, if you’re looking at adding a rooftop A/C unit to the the van, take a look at getting a Micro-Air Easystart, I added one to our trailer, it was super useful and worked great. It regulates the initial power needs of the A/C start up power demands so you can run the unit off of a lower rated power feed circuit without tripping, the true test was that we were able to run our travel trailers roof mounted A/C unit off of our 2000W portable generator no problem, without it, no way.
