Another glider question...

Hello everyone I'm new to the forum. I've Been thinking about becoming O/O or should i say I'm moving forward with this crazy idea...anyhow I'm looking for some opinions on used Coronado glider with 12.7L D60 3.42 rears 13spd with less than 500k mi on it. I'll be pulling reefer between 70k-80k gross and mostly West with exception of Cali. What are pros and cons of this set up, what can I expect as far as mpgs ( and yes I know it all depends on conditions and the way I drive) I do like to drive the speed limits but mostly because of the work I do "LTL" and will defenitally change my habits as a O/o. Is it hard to register glider in Illinois? I know all questions have been asked like 10k x but seem like everyone has their own take on it. Why do I want a freightshaker? I don't want to deal with all emissions crap and its really hard to find used kW or Pete glider so my options are limited.Thanks the help
