2007 Everest 344J Front Frame

[colemole]

Hello all
I have the above unit and I notice when I hook up the trailer the front drivers side by the bedroom slide corner deflects breaking the seal open for about 1 foot along the seam from corner of slide towards the front. . I resealed it but it opens when on the truck and closes when on the landing gear. Deflection is about 1/4 of an inch at the corner by the slide. Other side of the unit does not deflect. Frame issue? How do I investigate this to be comfortable what is going on?

Cracked or sheared vertical to horizontal welds on the left upper frame rail..Known weakness of the Keystone's of that time frame. Find a good welding/RV repair shop to beef up the frames.
