Okay, I'm just copying and pasting the following cuz I already typed it out on another thread!
"I adore my E3V2. It is the best double out there. My kids are 3 years, 1 month apart and it has been perfect.
In toddler/newborn mode... the toddler seat sits on the front of the stroller and will hold 44 LBS This should fit your DD for quite awhile until the baby is sitting up.
In toddler/toddler mode... the toddler seat sits on the back of the stroller and will hold up to 33 LBS Once the baby is old enough and sitting up, the baby can sit in the back (with the 33lb weight limit) and the front seat will hold up to 50 LBS
I was also able to fit my Snugride into the bassinet portion of the E3V2 and Aiden sat in the toddler seat up front... made quick trips into the store super easy with the new baby since the baby could stay sleeping in the carrier/carseat while we zipped in/out. I am getting a Safeseat1 for baby #3 and have already tried it out in the bassinet as well. It is a tighter squeeze, but I can still get it in there, yay!
I have had up to 70 lbs of toddlers, plus two stocked panniers (one is my diaper bag and the other holds my cooler filled with snacks, drinks, ect.) and it was still fairly easy to push.
We took this stroller everywhere with us until about a year ago. Then I got my P3 and now that goes everywhere indoors/short trips (malls, stores, ect.). However, the E3V2 still goes to the parks, zoo, amusement parks, stampede... anywhere I think Aiden won't walk the whole time (basically any day trips/outings). He is 5 years old, tall for his age and still fits comfortably in the front seat. Mikkel hangs out in the back and loves his space.
The only downside to my E3V2... my jealousy over the new Sport model... it has the jump seat that reclines, the easily adjustable handle, and that awesome green colour! I really want to upgrade to the new sport model (2007 model), but can't do it. My E3V2 is still in perfect shape after almost 4 years of owning it and going through 3 toddlers and a newborn.
Hope that helps some... if you have any questions, just ask."
Just to add (so it's relevant to your post): I haven't officially jogged with it yet. I have put the front swivel wheel in the fixed position and rollerbladed with it and that seemed to work well. Mostly we just go for walks though... maybe we'll get out the rollerblades this year, we have a really nice path that is close to us (if we can make it through all the construction!).
I would definitely get the panniers. They hold a ton of stuff and make the storage issue non-existant.
When my oldest was 3 and his little friend (that i watched all the time) was 2.5yrs, they fought constantly over who got to sit in the back seat... apparently it is the cool seat to sit in! Aiden would still sit down there if I let him, but he weighs 35lbs and the seat is only rated to 30 or 33 (can't remember which) when in the toddler/toddler mode. It holds 44lbs when in the newborn/toddler mode, I think due to the fact that the toddler seat is supported on the frame of the stroller when it is in newborn/toddler mode.
Hope that helps...
