I just bought a new 2010 33' Newmar Baystar back in April and finally bought a round of Koni FSD's a month ago to try and "soften" the ride. Went to St. Augustine (1100 mile round trip) and I honestly can't tell much difference in the ride....I keep 90 PSI recommended all around - I'm thinking about lowering the PSI to about 80* to make a softer ride....can I get any thoughts on this with similar experiences....?
Indeed, tire PSI has a material effect on ride quality. When you say "I keep 90 PSI recommended all around", is this based on your actual "going down the road weight?
Said another way, have you weighted all wheel positions and used the heavier wheel position on each axle to go to your tire manufacturer's load/PSI chart to determine the correct PSI for all tires on that axle? Or is the recommendation from another source?
Hey wolfe10 thanks,
Weighing is my next step - haven't done that yet (I'll see what it turns out to be and adjust accordingly) - the recommended 90 psi is on the sidewall and the mfg plate inside the coach (so I guess it's pushing 100 psi after it heats up) .....it's on an F53 chasis which I'm not impressed with but I guess you get what you pay for short of a DP - Bobby

Well as long as this thread has been reborn I should update. I traded that coach for the 2012. Same coach just one more slide and newer features. I have also dumped money into the suspension. Front end-roadmaster reflex steering stabilizer, rear-blue ox tiger trac bar and over all the Kelderman air ride system. I love what it has done for ride. Rides as close to a DP as I will ever get. Still experimenting with the air ride to find the absolute sweet spot.
Thanks ClassAGeek for the info.....there is no doubt the Koni FSD's are excellent shocks but I believe after reading the tire psi info, that is probably a big reason for my rough ride....my next trip is to Napanee, Indiana (home of Newmar for year end warranty fine tuning in April and I definitely will have the corner weights and the psi adjusted accordingly) Now I have 4 Bilstein shocks in the garage with 5700 miles that may very well have been doing the job, but my over-inflated tires may have been the problem all along....oh well...
