that E level system looks really good IMO. i bit more to instal since it has level sensors on each wheel but if your loaded in back or what not it will compensate for the extra weight which seems pretty cool. but then again it might also interfer with manual switch play time. so all depends on what youd like to do more. i personally would cheap out on manual system over the Elevel.
id love to have the dakota digital setup but with all 5 sensors it dam near doubles the price listed. so that sucks. but i think it is the best looking display. that backlit one looks alright but i just dont care for full light up faces like that! i just wanna see the numbers
