The basics: 2004 National RV Seabreeze 1341, Ford F53 chassis, Goodyear steering tires, 30,000 miles on coach, about 10,000 on tires, tires 4 years old, well maintained coach. I bought 3 months ago.
I have not been very happy with the ride of this since purchase, but I have no basis for comparison as I have always towed trailers before. The ride is OK, but harsh. Steering is fine, a little wander in wind and passing vehicles but better than TT was. My main concern right now is vibration. It appears to be in front of vehicle, some sensation through steering wheel. Vibration becomes most noticable between 40 - 45 MPH, most notable when accelerating slowly, or at steady speed in that range. Some times feel like it is "harmonic", my meaning that it feeds on itself. I suspect either front end components or tire balance. No noticable change when letting up on accelerator, so I am not suspecting driveshaft. At highway speeds, mine are 55 - 60 MPH, there is still some vibration but not as bad as at lower speeds. By no means consistent, sometimes accelerate right through that speed, when merging on highway for example, and hardly notice it. Slow acceleration is when most noticable. No indication of unusual tire wear, no feathering, edge wear, cupping or chopping. I am thinking of heading to alignment shop for front end check, alignment check and balance front tires, then see what happens.
Would appreciate your input and benefit of your experiences.
Also, MH is lightly loaded, me and co-pilot, 20 gals fresh, empty holding tanks, and not much gear, weekenders only at this point.
Have big trip coming up and would like to clear this up before I go next month.
