Moog and Bilstein is always a good combination---I've used those brands and continue to do so even today.
In fact just had installed Bilstein Short Wheelbase Motorhome shocks on my '05 E350 EB, 2wd only. They're a bit on the stiff side but the van so far is nearly empty---it'll soon house about 2000# of tools, boxes and such.
For a lot of applications Moog and Bilstein is a top-notch combination!
I bought my shocks from a place in San Diego area called AJAuto. Great customer service and I had them for the best price online in 2 days( I live in Az). The ride with this combo is night and day better
