Handling advise

[CaptainCal]

After 11 years of owning a 28 ft. class c ,I just bought a 2004 Safari Trek,29RBD with 36,000 miles. It is on a workhorse chassis but I do not know which model.
I only drove it for 30 miles on 2 lane roads and 15 miles on the highway. It would sway even when passenger cars would pass. I was hoping that a semi would pass to see what would happen but didn't meet any. I am 1400 miles from home base at my son's house and he has a place for me to make repairs.
What I need to know is what do I need to do to the suspension to get this rig to handle rock solid ?

The best advice I can offer is to become a member of Trek Tracks http://www.trektraxs.com/ That site is dedicated solely to supporting Trek owners of all ages. You'll find others there that have already addressed the issues you're experiencing. Welcome to the world of Treks. I've got a 2004 Trek but it's on the Ford chassis which are few and far between.
