All good, no down side, great handling, really outstanding braking. The side to side wobble on turning acceleration I originally thought might be related to the wider front wheel base turned out to be a loose axle nut on one side. Don't know why, but it was not fully torqued. I must have missed that on assembly as I don't think those things can loosen on their own. Coach is noticeably more stable in wind, even though our coach handled and drove well before we made this change and I initially didn't think I felt much difference. The difference is real. On this trip (so. Oregon to Santa Cruz, CA - 1000 miles round trip) we hit high winds going down the coast which previously would have made speed limit travel uncomfortable. Not so this time. Also less white knuckle stuff on the very narrow roads through SF on the way to the Golden Gate bridge and through parts of the Redwoods. The coach holds lane better and returns to center more readily if you do wander out of the lane
a bit. The ride is a bit softer up front likely from the spaced out front wheels putting more leverage on the torsion bars.

Our 78 Royale requires 91 psi in the stock rear bags to maintain proper ride height with the front at the factory height setting. I will be experimenting this week with air bag raisers to see how much lower the air pressure can be and still run at factory ride height. If that gets down to around 80 psi then there will be plenty of rise leveling range with the wireless air controller. More on that later, but for now the 3500 mile report card on Manny's version of the one ton front end is all A's. Highly recommended.
