Thank you all for the advice. It confirmed that little voice inside my head that said go with the bigger motor (175) and dont have any regrets. I signed off on the 175 as well as deciding to do the tandem axle this afternoon. This was the last crossover slot available for this 22 yr per dealer. Apparently he claims they had rhe order open since late 2020. Hoping for a May delivery fingers crossed. Now I just need to be patient on the electronics that may take forever as well.
