Hello All, I'm new here, I'm not exactly an expeditor but I do pretty much the same work. I haul medical equipment for Demo in all 48 States. I use a 2012 M2 Freightliner day cab with a Cummins ISB and Allison auto trans with a gvw of 33,000lbs. Loaded I gross 29500 lbs. Maybe this has been covered before. But we are looking at replacing it . My question is, Dollar for Dollar what do You guy's think would be best ? I am considering another M2 with the small extended sleeper which would be much the same as I have, getting around 8.5 mpg or the Cascadia Midroof 48" sleeper with DD 13 and Ultrashift. What MPG should I expect from the Cascadia ? I realize the Cascadia would have a much longer life, More power and comfort,but would have a far heftier price tag. I appreciate any thoughts and information. Best Regards, James
