I have a 2008 34' Alpine coach built actually July of 2007, 3000 miles on it and am wondering if it is worth it to add the motion control units and Koni Shocks? I have been referred to Spectra Suspension in Gilbert, Arizona by Precision Frame and alignment, as I am currently wintering in East Mesa, Az.. HAS ANYBODY USED SPECTRA. Also wanted them to check as to why my brake pedal is so hard. There is no label on the large reservoir in the engine compartment.

I don't know what hydraulic fluid that WRV was using for the brake booster system then, but suspect is was still the 15w 40 motor oil, if it doesn't specify differently. I just had mine changed to the Chevron Rykon premium 46 as talked about in many topics to date. I did find the Rykon to be a lighter grade when it was cool, more like the ATF used in the earlier coaches. Its spec sheet shows that it has less variance in viscosity with temperature change than the multi grade engine oil. The braking is better, but I can't say how much until I drive it a bit more. In the mean time, if you adjust the pedals all the way back toward you, I think you will find it to be better. That is what I use to do when having to do a lot of braking.

As to the other changes you want to know about, to a search on those topics, there are many posts about them.

Mel- our coach is #75780 and was probably completed shortly after yours. Ours has the same oil in hydraulics as in the engine crankcase (Valvoline Blue 15w40 IIRC). My braking is manageable, but I can't engage the ABS which I feel I should (sometimes I just like the vibrationnnnnn). When I change it I will get Rykon.

Most noticeable when driving over dips in the road and when coming out of driveways and turning. I felt it was the best single improvement I've made to my coach.
