Moving on from suspensions to frames. I'm picking up that the frame is either "I" beam or box or both, with box being strongest, "I" beam/box combo next & "I" beam weakest. What's the preference?
Also, the frame should be a minimum of 12" or more. Is this also the preference?
Thanks for your opinion.

The larger the frame, the stronger it will be and heavier. 12" I beam on an small trailer would be overkill, same for some of the box beam configurations. What kind of trailer are you looking for size-wise would be a better starting point. From there, the experienced folks on here would be able to better advise you of what is appropriate or recommended vis a vis the preferred frame set-ups. Its important to understand the differences, strengths and limitations but you should figure out what you want to do, what kind of RV will fit that goal and then figure out who has the best features, amenities and the best "bones" for your budget.
FWIW, Brian

Brian, take a look at the frame section on my website. It is in the New Horizons page, but is generally applicable.
You cannot make generalizations like I-beam is best, or box is best. It all depends on the application and structure of the metal.
I-beam in combination with box tube is very good. Each excell at a specific thing. Double box tube is also good. The key thing is to have ENOUGH frame of any specific type for the load and the cantilever.
Frames are tricky if you get into heavier coaches. One cannot say that any specific design is superior - you have to look at the application. One cannot say that any manufacturer has a "bad" frame, either, although it is popular to pick on Lippert. Lippert has had some very poor frames in the field. But so has almost every other manufacturer. There are just more Lippert out there....
