Some of our trouble areas

Well, we got her home, (all the way from Paradise, Utah!), Now for the fun stuff ~ There looks to be some water damage on the interior from a while back, a boogered door and back hatch, a missing glass louvre, & a giant blob of silicone from what the PO said the original owner said was from a 2x4 busting through?  I don't know ~ I hope we haven't gotten ourselves in too deep. For $550, though, it was worth a shot.
