I agree! I hope the Arrow IV's are single level MUs, and have A RFW like the SL-Vs do lol, I know the first set of seats in the first car is roped off on the SL-Vs, from what I read the second and third seats still offer a nice view. Not really a fan of the Arrow IIIs, they look nice, they was built by Budd and have a great sounding horn its just the seats on those things, I honestly think that if they had more pleasant seating for tall people like myself, I would be a fan of them!
But last I heard the replacement for the Arrow IIIs are gonna be multilevel, its unknown whether they will be Push Pulls or MU's though, I'm hoping for the latter, as more Push Pull multilevels would be boring.
