The following photo and article shows demonstrates what the Fix and Go kit is.
Your Fusion motorhome does not come with a spare tyre. It comes with a Fix & Go Kit which you will find in your boot in a small black case.
This is a tyre repair kit that can repair and inflate a flat tire in minutes so you can drive safely to the nearest tyre shop to get it checked and fixed. You can also use Campercare insurance with roadside assist built into your insurance policy and call for support from them and they will bring a spare.
See below a photo of what it looks like:
Follow the instructions carefully. Once used, ensure you purchase another canister to replace your used one. This Fix and Go will not damage your tyre.
