This is a really hard question to answer. All of us own something different.
I have a keystone. That aside, all of them are built on a assembly line and unlike cars there is no standards needing met.
Best I can tell you is to go to a local Dealer and see what you like.
Just to many different things different. One trailer is built in a dust free environment and another have vacuum sealed walls. To many different ways to do the same thing.
At $25 you can get a good Coachman, Cherokee, Gray wolf trailer.
I like Cherokee due to it is built by a bunch of Amish Folk. The people building that trailer really take pride in what they craft.
All opinion based.
