also keep in mind, most all brands had options, on build, as to centers on framing, 12"-16"-24" and so on, from floor to walls to ceilings
which honestly effect price/value, strength of things too
so its not just "X" brand to"X" brand name, unless all things are equally built like wise!
but I agree, ALL used trailers need to be gone over really good, as folks today, tend to be HARD on things, over load, tow at extreme speeds, and that all can make for welds failing faster than normal
hitting a pot hole at 40 and hitting it at 90 can be a LOT harder on things!
types of axles too can add value or not!
best advice before buying besides looking at welds really good, is TOW IT< take it for a rest tow, at slow and higher speeds and feel for vibrations and how it handles
they DON"T all tow the same, based on build, axle placement and well, design in whole!
