Hello I have been looking for an 04 to 07 3500. I have seen alot of trucks at just over the 200000 kilometer mark is there anything at this point to be really aware of I presently have a 95 12 valve with 156000 k . I know fuel consumption will be quite different. Alot of the 07's are probably lease returns. The only reason for chnging rhe 95 is it is regular cab and with the grand children I need more room so quad or mega is needed. Any big concerns I have noticed alot seem to have front and rear seals leaking one peddlar told me it was compression and that even if replaced no one would warranty the work. Seems odd to me. so any input appreciated
