2003 E350 Chateau - Smoother Ride

[Stevenr325]

So, my 2003 E350 Chateau is awesome, but my kids can't read in the back from all the bouncing. It is my wife's daily driver with the 4 kids and I need to do something.

Some info: 90% of the time it is just the family with some bikes in the back, 20% of the time we are towing a 24' trailer at 6000lbs with a weight distributed hitch and sway control. It also has a sliding door.

I thought a set of Yokohama Geolander AT-S 265/75/16 Load Range D (3000lbs) would help a little. The stock tires being 245/75/16 Load Range E (3045lbs)

My local shop suggests:
2" lift with new coils in front and blocks in the back, to fit the tires and clear the sliding door
Rancho adjustable shocks
Remove the overload leaf on the rear springs and install air bags

It would run about $2200 with out the tires.

So....Does anyone see any issues with this?? Handling? Towing? Brakes?

I know it won't ride like a Cadillac but I need to keep my kids teeth from rattling out.

Thanks for your input,
Steven
