By far the biggest bang for the buck is to find shade, park there...

We used one on our boat. It certainly works (unlike some posters imply) but I would suggest the dual hose units as for the same BTU rating, they do cool more because they don't draw in any outside air.

First question, do you have a 50 amp service? If so, add a second rooftop unit.
If not, then you have a couple of options, either add a second unit with separate wiring leaving it to a 20 amp cord which you would plug in separately from another source, or do the same with the portable unit.
You will have to add that second cord because the 30 amp main service simply wont be able to handle the load of a second AC unit and everything else in the trailer on it's own.

Holy snikeees, that's a nice camper! Just looked it up.

I'd say, don't worry about a solution to a problem you don't have, yet.

There's no reason that AC shouldn't be able to keep up unless you somehow "know" otherwise.
If your expectation is to lock it up in the sun, AC off, come back at 5 pm and expect the AC to cool it down in the next 10 minutes, you need to change your expectation. If you expect to leave both bedroom doors open, kids leave the camper door open most of the day and forgot about the window cracked open, and it stays cool inside, change your expectation.
If you want it to be a walk in beer cooler when it's 100out, not gonna happen either likely.
But with just a bit of care and common sense, there's no reason it won't work acceptably.

I have used a portable at home and it worked fine. My issue with the RV is that there is basically no extra space and good chance the vents will not work well with the RV windows.

Get a second a/c installed in the ceiling.

No you don't. My portable can go days and days and barely produce a few ozs of water. With the roof top A/C running as the primary source, the humidity is so low I only need to drain the holding tank when packing up to come home.

On the portables the condensate cools the condenser, evaporates and is expelled out the warm air vent.
Similar to a compressor fridge including the moisture from the defrost cycle.

I used one and it worked quite well. We only ave 30 amp so a 2nd ac was out of the question. I fashioned a board that fit into the slide window and had the exhaust go there and also ran a dedicated heavy duty extension through the slide from the ac right to the pedestal. As far as condensation there was not much after running this thing pretty much 24/7 for a week.
