Your wanting tech infomation we don't have...and also bashing all LCI frames is total BS.
Having owned a Fleetwood...Thor and Skyline built trailers which was bashed by a few individuals at that time, mine had no issues.
Thousands of satified LCI customers vs those that had issues some years back.
You will have to go to each trailer mfg and ask them those type questions. When I look at frames I go underside and see for my own self how its made and the type of steel extrusions the frame rails are made of.
And of course the trailers with the best frames is the one owned.
I would advise anyone looking at "lite" models to R&R their frames to their satisfaction.
