I just joined the site. I have owned 4 Rams, this makes my 5th. I have 2019 Ram 1500 5.7 Hemi and from what I have read I shouldn't be to concerned that my ECO light rarely comes on, I only have 250 miles on it. I read some very good suggestions on how to work the MDS, guess on my other trucks it was off. I'm getting really crappy miles per gallon right now and most are highway miles. I would appreciate any suggestions from the group on how to get better gas mileage and if doing all the programming and things will effect my warranty. Thanks!
