I wonder why Keystone is not installing this simple bracket on the frame when they have the frame built by Lippert.
It is OEM installed on many Grand Design RVS..
The origiinal design was made back in 2003 and if you look at the drawing it has been revised several times with dates in 2021
This bracket installed on all spring hanger brackets would certainly help minimize the possibility of folks breaking the factory bracket welds
Of course many of the broken spring hanger bracket welds are caused due to folks backing their RVs at extreme hard angles. this puts a lot of added stress and side load on the spring hanger brackets
The design is simple, low cost, and is also,currently being sold on Lipperts website:

These brackets could also be easily made using the drawing specs and then having them welded into place.
