As seems to be common nowadays my 2015 717 didn't come with a spare wheel, just a blowy-up type of kit, and I have never felt happy with this. As a result I have just ordered a spare wheel with the same tyre as is fitted to the van, but I'm not sure if I should go the whole hog and get a jack and wheel brace as well? People tell me it's best to rely on the breakdown service to change the wheel for me using their heavy duty kit, but what happens if I have a problem in the middle of nowhere or they are busy? If I get a jack, which one should I buy? Many thanks for any help. Bob.
