Smallest folding umbrella

My husband has DS often and sometimes we take his truck on weekends. I would like to find an umbrella stroller that will tuck partially under the back seat of his truck so we can keep it in there all the time.

What I am looking for is:
-Smallest fold
-Good for 4 month old however, if I have to wait until he is 6 months I can make do
-Good for travel
-Good for long stride. I am 5'8" and kick the wheels of a lot of strollers.

TIA

I would recommend a combi but they can be kind of short. However there is one they sell at babycatalog that is taller than the normal combis. Here is a link:

Combis have a very small fold because they fold down and then it folds into itself in thirds.

Maclaren Volo -- although you'd do best to wait until your baby is 6 months to use it as there is NO recline.
