Oh Golly, Bob, what a terrible thing to have happened. I am so sorry your Toyhome got damaged like that.
Your insurance company might have one of their RV estimators look at it for you. As you said, you don't want to have repercussions later on from other unseen damage. I expect that Camping World can see all that there is to see, but I would want two separate opinions if it were mine. Especially when the structure might be compromised.
Your Sunrader is almost impossible to replace, even if you did get another one like it, you would have to do all the little, and big things, that made it yours, all over again. Also, they are getting more scarce.
