I only used the trailer for cycling. The cheaper Chariot models are equally good and much cheaper than their top-of-the-line models, and unless you plan on riding offroad, the suspension is not needed. My Chariot (vintage 2000 if I remember correctly) is roughly similar to the
Chariot Caddie and served us for roughly 8000 km of all-season riding, even in snow. It has been almost waterproof. Only problem: the plastic door becomes brittle at -15 or -20 C.
That being said, I have seen a couple of MEC trailers and they seem equally well built. The fabric might be a bit thinner so it would not last for 5-10 children and I have no idea how waterproof it is, but the frame is equally protective. Check the hitch to see how easy the trailer is attached to the bike. I give 10/10 to Chariot for its EZ-hitch and have no idea how this one fares.
In both cases, I have no idea how they work for walking or jogging nor how easily they convert from one mode to the other.
As far as I'm concerned, another great contender is [
