I had an sr5 and now have trd sport. I can tell a big difference in the ride and extra small things like 120 volt in the bed etc. My opinion go with trd and upgrade that little at a time.I am looking at getting my first truck in like 10 years and was wondering if its worth the extra money to buy a TRD model or would I be better off getting a SR5 and upgrading the stuff myself! . Thanks for any help
