I currently have a 2wd 2010 sr5 runner with 135k miles and am ready to upgrade to a 4wd model. I don't do a ton of off roading, but would like to start. I'm in AZ, so weather is not usually a factor. Would li,e to install a leveling kit at the very least, and run 285's or maybe a little bigger. Is it worth it to pay for a trail version, or would a newer sr5 suffice? Thoughts? Thanks.
