I'm a little shorter and a little lighter (not much in either case) and come from a background of riding road bikes (so even my MTB is fitted with narrow city tires). But for the sort of riding you are describing I use a Trek Waubesa. Stock, it takes my weight without an issue (whereas I have to have the wheels of my road bikes especially built with heavy gauge spokes). It has the 8 speed Nexus internal gear hub (so you get the gear range needed for paved trailers but not the hassle/risk of derailleurs). They stopped the model this year but you should be able to find one in a stockist.


Caspian Blue '03 BA, Union Jack/Stars and Stripes paint, BUBs, Progressive 812s, and lots of chrome
