The bank statements, payslips and vehicle rego will be enough proof to show your residency. As long as these documents have the first 10 months address on it there will be no problem. You can also show the address proof with a combination of these three documents, example as first three months bank statements, next 6 months payslips etc. The negative side is that the case officer need to check more documents and so take little bit extra time. Make sure you do the certified copy and then upload to the online system.
Only 10 people are working for 887 visa and they are getting applications from all over the Australia. I guess out of 10, 2 or 3 people are/will go on the holiday or take the work off so the rest working people are 6 to 7 and that too 9 am to 4 pm working hours Monday to Friday including the break. Now, if there are no required documents or provided less or more documents available or have the all documents but the case offer couldn't identify in these cases I guess they even don't want to look at it and request the same or further documents. I have seen so many posts here about requesting the document which has already uploaded on to the system. Make sure you write the appropriate name of the file when you upload to the system so that the case offer can identify it properly.
Good Luck.
