Those cracks are from insufficient strength of the structure itself, welding them back up without a LOT of additional metal will result in the same cracks developing in the future, likely out of warranty.
Before any changes are made I would recommend you have a licensed engineer have a look at it, if the design is inadequate you will need a lot more than just some welding.
Yep! It looks pretty flimsy to me. It would be interesting to see/review Lippert's authorized repair specifications/drawings. In my mind, it's no surprise those "factory" welds cracked. I agree with some additional structural steel reinforcing, otherwise, IMO, those joints will just crack again. Who's going to perform/pay for them is now the question. Good luck!
