I decided recently to expand N collection with some RC Autoracks and an Athearn Automax. In conjunction with recent buys I also decided that I'd upgrade the wheel to FVM metal wheels. So referencing my library of proto photos I selected the 28" size wheels. Being primarily a Z kind of guy, I was excited to have the prototypical size wheels available. However while waiting for the cars and wheels to arrive I notice that some here mention using the 33" wheels for their RC autoracks. Skip forward to today, all cars and wheels in hand, I begin replacing the wheels. I don't notice any immediate issues with the one MTL or any of the RC autoracks, but when I swap out the set on the Athearn Automax I realize the trucks are larger than the 28" wheels. So go back and double check at the RC trucks, since the RC use the MTL trucks, with the 28" wheels installed. They clear the track and cars move freely but not a lot of clearance. The other thing I notice is that RC and MTL use the barber roller bearing trucks, but the comparing to the photos the standard roller bearing trucks appear to be a closer match IMO.
Remembering DKS's review off Z trucks and couplers, and some of the fidelity issues. I am curious to how how the N scale MTL trucks stack up. Is there a N-scale truck that would be a better fit? I'd like to be able to stick with the 28" wheels but can switch to 33" if need be. One other note, converting all to body mounted couplers. The plan is for these autoracks to be a unit train so they are only coupling with similar cars.
So I decided I post here for some sage advice from those more well versed in N than I.
