That aluminum trailer repair record is not so good.. but I think you knew that! The trailer quality comment seems valid for a lot of the cheaper brands. The gauge of the metal used in a frame is a factor, as well as the shapes and structural design, IMHO, and may well be lighter in some cheaper trailers.
Some of the higher end brands seem to have stayed good, at least for heavier trailers that get a lot of hard use, like for construction equipment trailers. My 2021 PJ equipment trailer seems as solid as they used to be.
IMHO, a 23' enclosed trailer will be a big load for that F150, but at least it sounds like a long wheelbase truck, which will help. How far do you tow and where? If not too far and with only a few long grades like going up to the UP, then some patience on those grades may get you by just fine. Some fellows can't stand going 50-55 mph up a long grade.
We are on long end of the towing spectrum, and tow 300-2000 miles per trip each way, and through the mountains in East and West, mostly for work. So we have had only 3/4 ton diesels for towing for almost 40 years. The weight advantage of aluminum is not there for us. But that's probably not your situation.
