Just got back from MN--2500 miles. We live in Austin TX so it was straight up and down interstate 35. I had motion control units (4) put on. Also safety steer and four koni shocks. I can't begin to explain the difference in the ride and handling. Many before me have mentioned how great these 3 things improved the ride, handling, less fatigue ,walmart wobble. It's is unbelievable.
I went to Precision Frame & Alignment, Inc. the owners name is Dick Lorntson. He also is a motorhome owner. I found him on the internet RV suspension and tires are our specialty
. Sometimes things just work out great even on the net. He has a wonderful shop, very professional in Elk River, MN. phone 866-473-2632. He does rallies central and east. Also flushed the master and brake lines and fixed the pivot arm. So if you're ever in MN check out Precision.
You won't be sorry and the price is right.
