So if we choose the metal frame, if we go with a folding frame is that as durable as the plain welded one? We thought about the bolt together but isn't the one that folds a combination of bolt and weld? If choosing the frame to build on is this complicated, well, to me anyway, I just hope the choices get easier.

I just feel that the frame is like the foundation of a house so am probably over thinking it - I over think everything so this will probably really be a process!
