Indeed, 4 in the 90 gal Comanche (the one in the ad is the pre '62, two 30 gal bladders). They put an aftermarket 15 gal metal tips on the one in the ad, so cheaper to maintain. In fairness, bladder shenanigans are not unique to the Comanche. I was thinking more along the lines of having some major tweaking of that old gear (AD or otherwise), and/r transmission woes, and have a no-kidding half a year backorder on gear conduits because of some random time of year and the nature of stock procurement when you have one boutique supplier keeping the entire fleet from the salvage yard. AOG city. No thanks.
Piper really pooched it not continuing the category with the Dakota RG. A PA-32R is nowhere near a category substitute for a Comanche (the argument often made for no Dakota RG). Apples and cantaloupes.
