When Smarty first came out I got one. I was very pleased with its effects on my 2001 Ram 2500 truck. I have been away from TDR for several years and use my Smarty only when I'm towing because it does help in certain areas. I just found out about Revo when I renewed my subscription but I don't know if the Revo upgrade will help me while towing. At 75 I don't need a hot rod! Been there done that! I just would like to know what does Revo do? Will it actually help my truck when towing in certain conditions more than the older software? Can anybody out there help me!
