I also only have the level one charger and am living in a big arse 5th wheel[because screw rent prices]which doesn't have an extra 30 amp outlet anyways.
Your 5th wheel most likely connect to a Nema 14-50 plug. Depending where your trailer is setup (campground, friends field, etc.) do you have access to 220-240V?

If you do have a decent supply, I would buy a dumb level 2 charger like a Duosida or similar. When you get home unplug the trailer (run on battery) and plug the car in for a couple of hours, this will do the bulk of the charging. Then plug the trailer in and use your level 1 charger to top up over night.

Even better would be to make a plug splitter so you can run both at the same time, the 5er will only have a significant draw when you are running the air conditioning or if you cook with electric.
I built my own for about $30 worth of parts but you can spend more and get one already built with molded ends. Not sure if you can find it cheaper but for reference, Amazon has a couple starting at $89 that I could find.

As you said you're probably never using close to 50a, either get a EVSE that allows you to set the maximum current(such as some Juicebox's) or a cheap 16a Duosida like you said. I can't see the RV would ever draw enough current as to need the extra 16a drawn by the Duosida :)
