IMO if a trailer is much over two tons I would be looking for 4 tires. For me it isn't about length it is about weight. You can get tires that handle more than 2000 pounds each and I choose not to go there. A T27 has a dry weight of 3390. Add propane, water, waste, clothes, beer, a bicycle, a tricycle, more beer well you get the idea ...... you will be over 4000 pounds. Can it be done ... sure. Wanna have lots of fun with a blow out and one good tire .... well that can be done too. I choose not to go there. That's just me.
The hardest trailer on running gear is a newer single axle 24/25 footer. There is more load on one wheel/tire combo than load on one wheel/tire combo of a 34 footer with three axles. Get a flat with a multiaxle trailer chances are extremely good you won't need jack to change the flat. Just a piece of wood. And no worry of the trailer weight pressing down on a rim with a flat tire, grinding that rim to being not usable. That just doesn't happen. Boondockin' and Burning Man, those are some awesome places to have some redundancy. 'cause it ain't like camping in an asphault camp site.
