Mats - I think I saw a post about some nice mats at Suncoast.com in FL. Check WeatherTech or LLoyds also. I've not searched for rubber floor mats. My rubber trunk mats came from WeatherTech. They do not have a lip, however. Just a bunch of small cavities to hold liquids.
Starting after such a short period is not likely to cause a problem. Especially with maintainer to keep battery happy.
Hope you really enjoy the Box after it fires on first try.
And WELCOME.
