Spare tire for 2014 MB 3500 Sprinter

I can't help with your question, but just an alternative viewpoint. Our 2005 LTV Free Spirit Class B had its spare on the back door and LTV used the Sprinter spare spot under the floor inside back doors as what they called "basement" storage that comes in handy.

After 150K miles of travel with the spare, at a Class B RV rally, the question came up about the need for spare tires brought on by the fact that newer Class Bs often don't have spare tires. After hearing the pros & cons, I decided to live without the spare tire. The reasons were (1) only one flat tire in those miles (and that one happened when it was parked in a family member's driveway and the tire slowly went down due to a nail picked up the day before, (2) the need to drop the tire down when we needed to open the door on the side the spare was on, (3) we added a screen across the area inside the back door opening that required more dropping the tire when we wanted to open both back doors for a good breeze through the RV, and (4) our Progressive insurance on the RV covers 24/7 Roadside Assistance.
