Probably made in the same factory

It's going to be kept in standard condition with the camper body being detachable so it can also be used for bike & rubbish hauling.
I can weld the frame but wonder how people who have left it "bolt together" find it has lasted. Do the bolts work loose, too much flexing and such ?
Thanks.
