Anything heavy I would use the 210 just because it's nice with all of the safety built in. I wouldn't tow anything with the 310 myself, but I know some people do pull some light stuff with it. If you never tow anything super heavy the 275 is a great all around tune because you won't have to reload every time you hook up to a trailer, I never unloaded my 275 before I got the 310, and towed about 10k with it as well. For unloaded highway mileage my 275 and 310 get about the same.
