Really Harsh Ride

Finally took the 2010 Sightseer 37L out on it's maiden voyage.
(NY to Tenn.) I was really surprise to feel how hard the ride was at a relativity low speed. At 62 miles per hour, even slight bumps cause a harsh / noisy shaking. The tires are set to the correct pressure. Could this be caused by worn front end parts, or that's just the way these ride.

By " correct pressure " do you mean the pressure on the side wall , or on the coach manufacturer's decal on the interior wall, OR, have you taken the coach to get four corner weights and set the tire pressure according to the tire manufacturers inflation chart?
Getting corner weights and using the tire manufacturers charts is the first step in any , handling / ride, problem repair.

I agree. And it would be helpful if the OP would say which chassis he is driving.

Inflate to mfgrs, tire placard stated air pressure. Those load/inflation charts are deceptive and misleading. The RMA=Rubber Manufacturers Association published a tire guide, of which, CH 4, pg 51 pertains to MH tires inflation pressure. Michelin, Goodyear, and many other brands are members of the RMA, their websites display the same tire inflation admonitions:

"_However, never use inflation pressure lower than
specified by the vehicle tire placard, certification
label or owner’s manual."

I'll second this. Always use the pressure that the NHTSA placard on the vehicle says.

Bear in mind that underneath it all is a box truck and it will ride like one. Our 2002 F-53 did.

After pricing out all the various ride improvement mods, I realised that, if I did them all, I wouldn't be able to afford to use it for a couple of years. With a utilisation of about 4000 miles a year, we decided to live with it and drive more conservatively.

We finally sold it after realising we hadn't used it once in the 2014 season.
