I sent you a PM!!
If you still have smoke smell - once the insurance company has ok'd the cleanup, and after the cleanup by fire and water restoration folks, then do the following:
Check with all your local car dealerships, they probably have the name of a company that attends their facility to place a "smoke canister" inside vehicles where the previous owners have smoked cigarettes. We had a company place two of these canisters inside our RV and it really worked - "bubblegum" was our choice of deodorizing smell, better than smoke smell that it got rid of.
Be sure to keep track of any time that you or your husband spend cleaning or removing items from the fire incident, our insurance company paid us a couple of thousand dollars for our work/time - we also took lots of pictures - which was to our benefit, and submitted notarized statements from our neighbours to attest to our time spent working on this incident.
Don't be discouraged, it will seem like quite a process, but in the end will probably be better than before.
Hugs to you all.
