Just a thought, folks. I had the same feelings when we first got out 2011 378. The motorhome would wander on the road, felt bouncy and was a handful to drive. Had the suspension checked at the dealership where I bought it and they found nothing wrong! Mistake made...why did I take it to the dealer when it's a chassis problem????? The dealer is not a truck chassis expert. Took it to a FORD truck dealer and the problem was promply found. 65 PSI in the front left tire, 95 PSI in the right front tire and "around" 80 PSI in all four rear tires. Aired all tires to 90 PSI by the FORD folks and WOW! Drove it across the Dames Point bridge in 25 - 35 MPH quartering wind and a solid, controlled ride as good as a breadbox going thru the air at 55 MPH can expected to be. Then did the "cheap suspension fix" on the front axle. I'm well pleased with the handling now. But the biggest improvment was the tire pressures!!!!! Probably came from the factory with incorrect pressures and was never checked by the dealer. Guess what I do everytime we get underway......CHECK THE TIRE PRESSURES! And now carry my own 150 PSI compressor.
