We're in Northern Minnesota on the Gunflint trail - Unbelievably beautiful up here. We went fishing and thouroughly enjoyed the time here so far. We leave on Saturday and onto a new adventure somewhere else. One question though - trip up here was a little nerve wracking 300 miles on some rougher roads. When Semi's pass I am white nuckling it. I am pulling a boat and when they come up they just about blow me off the road. I heard the stories about being blown around from a semi. I'm wishing I had some sort of steering stabilizer on it. One bothersome thing is when we hit a little bump it feels like the wheels are going to come thru the drivers and passenger seats. I have what looks like sumo springs on the coach but they are orange in color not that they do anything for bumps anyways. Can worn out shocks cause that loud bang. Springs wore out? Any ideas would be appreciated. 2004 (348) 8.1 Workhorse, 36 ft long. New tires all around.
