I have a Bikes To Work 64AW trailer. It certainly will be big enough for any need. It carries 300 lbs.
Yes, a large trailer like that does surge. It's momentum is its own. The surging is more pronounced when it is loaded. More like a large insistent dog than a jerk though. Mine has only low sides, but you could build tall ones. The bike stops fine. The handling is fine though I do have to be sure to watch my left heel when starting to avoid heel strike.
Bikes At Work trailers come in a variety of sizes. Mine is the second largest, and the widest.
