Hi, This is our first post. We have a 2008 2551. We really like the Rv, but it really wanders on the road. I have to really stay on the steering wheel. Any ideas of a good fix for this? thanks
Welcome!
Yes there is a lot you can do to resolve your troubles.
What year is the chassis....a 2007 or 2008? Is it an E350 or an E450?
Being a used rig, you don't know what the previous owner has improved upon, and what was not done.
Check your front and rear stabilizer bars. If the front bar diameter is 1-3/8" and the rear is 1-1/2" then your bars are already upgraded. If their diameters are under an inch, then I would replace them with heavy duty aftermarket versions.
I would replace stock shock absorbers with Koni-FSD shocks.
I would upgrade a stock steering stabilizer (the horizontal shock-looking thing attached to the steering linkage) with a heavy duty better type. I have a Safe-T-Plus and like it a lot.
After those four things are confirmed as "upgraded", you should be a lot better. Also get a wheel alignment and make sure you have the proper tire pressure. Too much air wanders the rig more than too little. Don't just put in 80 psi, the max stated on the tires. Follow Phoenix recommendation on the door sticker.
I had a shop upgrade our 2007 2350 as I am suggesting to you and the rig handles beautifully since, and that was done 8 years ago.
