Had the AV into the dealer, to check the frount end. I thought it was a little loose. Before I took it in I checked the tire pres. I changed the pres. from 30 to 40psi. The dealer found the allignment out, fixed it up. The radio was replaced do to it was loosing time. The truck now feel ALOT more stable I can especialy notice a big improvment in the wind. The dealer Saskatoon Motor Products was excellent. The truck is a much more stable machine.
