To all the HO manufacturers out there a 50 ton solid bearing ASF A-3 Ride Control truck would be great.  I was hoping Tahoe would do them, but no joy. Currently we have the Kadee HGC truck which works for Kadee cars but can be difficult to modify for other plastic and resin cars. The other option is the fantastic Kato truck but the non-standard axle length is problematic for those of us running code 88/semi-scale wheels.
