Not to be rude but your dealer messed it up twice and now you have someone to fix it but does not know how to attach the wall to the floor or at least does not what it is supposed to look like? If they need pictures to fix the wall do they know what they are doing or is this someone that thinks they can fix it but needs to know what it is supposed to look like?
I understand the dealer messed it up "twice" but you may want to find a "RV collision repair center" to get the work done correctly. On a 2018 camper you would want it to be correct. Then send the bill to the dealer that damaged it in the first place.
Sorry to be direct but you paid a lot for your camper you want it done right.

Sorry if I came across a little strong. Hopefully someone will post a picture or two. I guess I should have asked if the person wanting the pictures has any experience with RV construction. Anyways I wish you the best of luck. Just my opinion and its worth what its worth.

We have a 2019 SST 33SI, but unfortunately it is in storage right now. We might be heading there to do some work in the next week or two, so if you can wait that long, I can take some good photos of the back end for you. As far as I could tell from our research when shopping, there were no major changes between the '18 and '19 models.
Another possibility: look online and see if you can find a dealer that has a unit in stock and see if they'll take photos for you. Maybe offer to buy them lunch via delivery for helping you out?
