'72 Tradewind frame question

I purchased my 72 gutted and the PO had already replaced 2 main pieces of the frame running out to the bumper. Apparently rusted from the rear bath. The belly pan was also partially eaten away as you can see in the pics.
My question is, did the PO neglect to add back any rear outriggers? I have not found any pics on the forum of a 72 bare frame for reference. Any pics, dimensions, drawings and advice would be appreciated.

p.s. i've added 2 pics of the PO welds. They look ok but the 2x2 sq tube he has for support from c-channel to c-channel doesn't look like enough support.

Yes there should be some outriggers to support the shell. I would say there are two to three missing on each side.

On my 68 there are no outriggers past the last main frame crossmember. Yours look OK.
The floor is the only support in the curves in the rear.

Looks OK. I would have welded a plate across the lap joint in the channel, but thatís just me over-engineering things.
The wet bath wonít cause as big a load as a full one.
If you havenít already, search the treads on water intrusion through the joint at the bumper box cover and body into the floor.

I would consider putting a plate across the welded area to add more strength to the welded area. This would be a plate that would be welded across the center section going from top to bottom. The PO should have made an angled cut where the old beam meets the new beam. It will fail first at the weld and rust first there as well. My 81 center bath Excella II has outriggers in the last 4 feet of floor. This may be a rear bedroom addition to the floor that they did not think was necessary with the rear bath where most of the floor is covered with bathroom fixtures. It may also be something that changed over time.

I have a 1968 Ambassador 28'. From the rear axel to the back I have 3 out rig supports on either side. You might be missing some.

Here's copy of the chassis from my service manual. Might help a bit.

Thank you everyone for your input. I think I will take Toms advice and weld plates over the lap joints. Also, from the frame PDF supplied by Tom, it looks like I have all my outriggers but I need an added brace across the back directly under the shell. I'm sure i'll have more questions when I get the rest of my floor up.
Thanks again everyone!
