I have AAA RV, but I would never travel without a spare and the tools to change it if needed. Had 3 blowouts on my Class C(s) over the course of 26 years; glad I had the tire/equipment. My current Class A has a 19.5" mounted spare and tools in a side compartment under the bed (in the slideout). Yes it's high, and yes it would be a bi_ch to get out/in. But if it is needed, it IS there, and I am not relying on whatever tire roadside service can get/find, nor am I dependent on whether or not I can even REACH that service (cell signal) nor whether they will actually come to me (often boondock off the beaten path).
I also know that I can remove the platform under my bed mattress with just a few screws, exposing that spare tire, so if I CAN'T get it out/back in from the outside, it COULD be rolled in through the door and into the bedroom, worst case scenario.:D
