As an FYI - almost 50 years ago I worked in production - not quality by any means - cabinet shop for about a year. I ran a large panel saw cutting sides and bases for cabinet cases. Back then, I could tilt up 3 sheets of 3/4” (nominal) hardwood ply onto the panel saw to make cuts. Now I have to breakdown one sheet of plywood so I can carry a part of it. Those were the days.
Now back to your build!

In the trailer, the cold air coming out is drawn from the room, but so is the air used to blow across the condenser (exhaust hose). That air must be replaced in the CTC so it will pull hot air from outside and create a slight negative pressure in the CTC if you have it sealed up well.
Bottom line, it will never cool the space during the day and will run constantly. At night, it may keep up due to cooler ambient Temps.
Not trying to rain on your parade, but I learned this the hard way in my first CTC years ago.
Lots of discussion on these threads about this. A two hose system would be much better.

Both hose lengths would only be about 20 inches to get it through the floor.. shouldn't need fan assist to push or pull the flow of air for the vents.

If you could make a shroud and pull condenser air from outside, it would help considerably. That is what I did with my portable in my first CTC when I realized what was happening. It was better, but not super efficient.
I'll try to find some old pics and show you how I made the shroud. Basically used a vent hose flange cut in a cookie pan and used weather stripping to make a seal and bungee cord to hold it tight.

Great conversion on the one duct to two duct portable air conditioner. Can't wait to see how it worked. I suspect it will be a significant improvement.

Good luck.

So, I'm going to go through the side of the trailer with the AC, using 18" full extension drawer slides making a slide out on top of a short cabinet inside the trailer.

That's what I did on the trailer:
