I have installed many of these but not this exact unit.
Progressive Dynamics is a good brand but this one is way overkill for a vintage trailer. A big box like this will also take away from the vintage charm.
In a vintage trailer, you should only need 4 circuits (5 tops) for the 12 volt side of life. That would run a couple of lighting circuits, the cigar plug and pump, and the Fantastic Fan. One extra circuit could be added for what have you.
Most vintage trailers are 15 amp. When upgrading, 30 amp is more than adequate. That would be a lighting circuit, extra outlet circuit, and maybe a 20 amp circuit for appliances. Of course that means you will be using a 30amp inlet along with the heavy cords.
My trailers are wired with a 110 service box with 2 breaker slots. If you use twin or tandem breakers, 4 will fit. I use a separate 12volt fuse block usually with 6 available fused circuits. Both are often under the dinette seat but can be mounted in many locations.
Hope this helps. If your trailer is large and long, it's possible the PD box would work for you.

I'm not a fan of such an appliance that combines everything in one box. If one component fails, will you have to replace everything? Rather, I like a separate small 30 amp shore power box to 120 volt outlets that you can plug in a charger/converter. Then you can build your own fuse banks as well. I agree that the unit you are looking at is overkill.
