JD you got it right. I got mixed up in the brain.

Wow, the the tensile strength of 3/8 steel is over 4000 pounds, but when you look at that picture, you see that divot right in the middle? It looks like it is right at the top of the gusset. I see some rust, but am wondering if it's a cold weld at the top that started that crack. I was going to weld two gussets both sides. Maybe I should just go with Jayco's bracket, but I have a big trip coming up and they can't get the bracket till after. I asked, and they won't let me install it cause it's a NHTSA recall and I'm a licensed mechanic. I think I'll try to rig up some temporary support in case it breaks so it doesn't hit the highway. Sorry or what happened to you Bduck.

Your photo, however has created a question in my mind that I hope someone can clarify. My set up looks roughly the same, except the piece of channel that holds the pump fits flush to the rail of the chassis and they tack welded the channel to the chassis rail (at the factory).
The photo appears to show the channel extending well below the frame rail. Is that correct, or is it just a camera angle thing???

Here is how I fixed mine. It hangs down also. I did this two years ago when I noticed the potential problem, long before Jayco did their recall. Not so pretty welding, but very effective fix. It is from the frame to the upper part of the bracket, taking the whole load off of their L set-up.

Just spent some time looking at these photo's with my son-in-law who does steel fabrication and welding work (tig, mig and stick). When he looked at the pic with the arm extended below the frame his initial reaction was something along the lines of "what brilliant engineer thought this was a good idea". He explained that while steel is strong, it does not handle flexing well over time and get's brittle. I this case, that is why they were breaking at or near the weld. The Jayco gusset fix adds nothing because the added piece is not welded where it offers any support to the arm that the pump is suspended on...just adds more weight.
In my case, the channel is flush with the bottom of the frame rail. He pointed out that this reduces the stress on the original weld area, but still is not ideal. He said that in his experience, welding to the truck frame rails is not allowed after the original manufacturer....at least on commercial trucks (he doesn't know on motorhomes.
When I get this back from the dealership service department, I want to see what they actually do as the gusset will likely not fit and with the level of professionalism I have seen at my dealer, they will either do nothing or they will screw something up. After this is all done, I think I will have him fabricate a system that offers better support (he has a plasma table for making AR 500 targets, so should be able to come up with something) then weld it up. It will be impossible to avoid welding to the frame, but not sure what else to do.

That's how mine is. I sent this photo to Jayco and they said no repair is needed.

I posted a couple of pictures on the "Class C Motorhome" Thread titled TSB #19-022 Leveling Jack Hydraulic Pump Mount Bracket Reinforcement. They may give you an idea what the new bracket looks like.

Had our 2017 Greyhawk in for some minor, end of warranty repairs and they also found we needed the recall leveling jacks fix. Surprisingly, done in record time too.

It looks like the bracket failures are related to the LCI (Lippert) levelling system, which has a physically larger pumping unit and must have the bracket which hangs down lower.
My Greyhawk has a 'Equalizer Systems' leveling system, which enables the horizontal part of the bracket to be welded directly to the frame.
