Dodge Ram Wagon 3500 Reviews
One ton van used for wheelchair duty so it carries one or two wheelchair folk and one driver and maybe another passenger so not carrying much weight. I was told by dealer and independent that having to do upper and lower ball joints and one control arm at 43k not unusual. I:t was under Warrenty ,so not so bad. But now, at 70k it is starting to clunk again. A/c has had frequent breakdowns from blower under dash, to fan only works on highspeed, to rear a/c out again, parts can take 2 weeks for dealer to get ( and that was in 2003!!)
Its a big box and can haul lots of stuff. Front seats are fine takes forever to stop but its a big box. Ran it across desert in cross winds to Ca coast and it did fine at 70+mph.
has a 411 rear and big V8 wanted the limited slip and only way to get it so it gets about 11mpg
dealer takes the Ram in name seriously rammed it twice while in for service warentey over so now go to independent guy. He is much easier to deal with than 2 dealers I tried.
