I posted a few weeks ago on the subject of PC offering a F-550 chassis and did not get much response. With all the discussion of weights coming up recently I do not know why the 550 is not looked at as and option? I realize the engineering costs , etc...are significant but the F-550 sure makes some sense to me as it would offer significant more load capacity, more comfortable cab area, diesel option, and a better ride. I did very briefly speak with Kermit about this subject and he said he was sticking with the E-450. Thanks
