We had the Burley D'Lite (
https://burley.com/product/dlite/) before the kids outgrew it.
Really liked the trailer and used it a ton. Should be noted that towing heavy loads (2 kids + gear) is an interesting experience on hills and/or streets with subpar bike lanes.
Things we liked about the D'Lite:
* Suspension: Spring suspension gives just enough to keep kids comfortable on bumps and rough roads (pulled them once on my mountain bike on dirt roads). Some of the other trailers don't have this, which can make for a harsh ride for the kids.
* Easily folds: Wheels, hitch come off and store on the folded body. Great for bringing on adventures in other areas.
* Flexibility for different weather situations: Built in rain shield and screen. The screen keeps rocks/debris from hitting the kids while still allowing for airflow. Adjustable sunshield.
* Trunk: Good size area behind where the kids sit for groceries, picnic basket, etc.
* Optional accessories to convert into jogger and stroller. We usually kept the small stroller wheels in the trunk area mentioned above. Allowed us to ride bike paths to destinations, lock up the bikes and quickly convert the trailer to a stroller. Supper nice!
