What jet tender...?

I've got a 285 that fits in a Targa 43 garage deflated, (probably takes about 40% off the width), so I doubt you'll have any issues
 
Does the size alter much on the mini jet if you let all the air out, not sure if it would fit in my garage.

I am guessing you mean the length? Only ask as to fit in in my garage I also needed the quick release wheel. Guess it would go down by around 10cm, maybe more? What is the max length of your garage?
