I have a 2019 c5500 4x4 21ft rollback 55000 miles Its being back to the dealer once for a def issue 2 sets of tires and 1 set of brakes The ride is quite harsh and the turning radius is not like my old ones I put on 22.5 tires hoping to get more miles out of them (19.5s suck) I get 11 mpg Over all I am pretty satisfied Would buy another one but with air ride and 2wd Mlke
