Well after 4 years and aprox 15,000mi of only doing normal maintenance, my truck decided it wanted more one on one time with me in the shop. When we where 3hrs away camping last weekend the rad started leaking from the top solder joint. A bit of JB weld got us home pulling the camper. Had to pull rad and take to the rad shop to get it fixed. Really the only other break down was 5 years ago my spal cooling fan died, I replaced it with Derale.
